Symptoms of pregnancy in each week (35 to 40)

Week 35

Baby: Your baby measures about 20.25 inches from head to toe and weighs more than 5.5 pounds. Lungs are almost fully developed, but if born now the baby would probably be put in an incubator. It still doesn't have enough fat deposits beneath its skin to keep warm outside your womb.

Mom-to-be: Your uterus is about six inches above your navel. By now your weight gain is probably between 24 and 29 pounds. Your doctor will test you for Group B streptococcus bacteria between now and 37 weeks. You may be getting more uncomfortable and not sleeping very well. You also may be getting more anxious about the labor and delivery, and you may even be moodier and more irritable.

Tip for the Week: Be sure you've collected the necessary baby clothes, equipment -- especially a car seat -- and furniture to get you through the first few weeks, at least.

Week 36

Baby: Your baby measures about 20.7 inches from head to toe and weighs about 6 pounds. The baby may drop lower in your abdomen, usually assuming the head-down position after having frequently assumed other positions during early pregnancy. The brain has been developing rapidly, and your baby is practicing blinking.

Mom-to-be: Your uterus has grown bigger these last few weeks and is probably up under your ribs. But you're in the home stretch; after this week you'll be seeing your doctor weekly. You may be alternating between fatigue and extra bursts of energy. You may also be experiencing increased backache and heaviness, constipation, heartburn and discomfort in your buttocks and pelvis.

Tip of the Week: Start stocking your freezer with foods that can be easily popped into the oven or microwave after you bring your baby home. Chili, casseroles and many other dishes can be prepared and frozen ahead of time for use later.

Week 37

Baby: Your baby is about 21 inches from head to toe and weighs almost 6.5 pounds. Baby is getting rounder every day, and skin is getting pinker and losing its wrinkly appearance. Baby's head is usually positioned down into the pelvis by now.

Mom-to-be: Your uterus may stay the same size as it was for the last week or two. Your weight gain should be about as high as it will go, about 25 to 35 pounds. About this time, your doctor might perform a pelvic exam to help judge the progress of your pregnancy.

Tip of the Week: Just in case you deliver early, consider packing two bags for the hospital. Pack one bag for you, with warm socks, a robe, lip balm and everything you'll want during labor. Pack the other bag with the newborn items you'll want after your baby is born.

Week 38

Baby: Your baby is about 21 inches from head to toe and weighs about 6.8 pounds. Most of the baby's downy hair, lanugo, and whitish coating, vernix, is disappearing. Your baby is getting its antibodies from you to protect against illness. Baby's growth is slowing, but fat cells under skin get plumper for life outside the womb. Almost ready for birth, your baby would do well if born now.

Mom-to-be: You're probably not getting any bigger, but you may be feeling more uncomfortable. Make sure you have a bag packed. It won't be long now -- 95% of all babies are born within two weeks of their mother's due date.

Tip of the Week: Consider whether you'll circumcise your baby if it's a boy. Circumcision isn't as much a medical issue as a cultural or religious one.

Week 39

Baby: Your baby is about 21.5 inches long from head to toe and weighs a little more than 7 pounds. Toenails and fingernails have grown to tips of toes and fingers. Muscles of your baby's arms and legs are strong, and he's practicing lung movements. Baby's head has dropped into the mother's pelvis if he's head-down, which allows you to breathe a little easier.

Mom-to-be: You're probably feeling quite large and uncomfortable. Your uterus has filled your pelvis and most of your abdomen, pushing everything else out of the way. Your center of gravity has shifted, so you may be clumsier than usual.

Tip of the Week: Watch for signs of labor, but don't get too obsessed. It could happen soon or still be weeks away. Some differences between false labor and contractions: False labor pains usually concentrate in the lower abdomen and groin, while true labor pains may start in the lower back and may spread through the entire abdomen. Real labor also becomes stronger and more powerful as time passes.

Week 40

Baby: Your baby's length is about 21.5 inches from head to toe and it weighs about 7.5 pounds. Boys often tend to weigh a little more than girls. Reflexes are coordinated so the baby can blink, close his eyes, turn his head, grasp firmly and respond to sounds, light and touch. More lanugo falls out, but some may remain at birth on shoulders, folds of skin and backs of ears.

Mom-to-be: Birth should be soon now, but don't worry if your due date comes and goes. Only 5% of all babies are born exactly on the due date. It may be more difficult for you to get a good night's sleep because it's hard to find a comfortable position, but try to rest as much as possible, with your feet up if you can.

Tip of the Week: If you think you're in labor, don't eat. Even something light in your stomach can cause nausea.

Symptoms of pregnancy in each week (31 to 34)

Week 31

Baby: Your baby measures about 18 inches long from head to toe and weighs about 3.5 pounds. Rather than hearing vibrations, baby's nerve endings in his ears are connected now so that he can hear distinct sounds, like familiar voices and music.

Mom-to-be: Your uterus now fills a large part of your abdomen, and you've probably gained between 21 and 27 pounds. You're probably feeling increasing excitement and anxiousness about the birth -- it won't be long now.

Tip for the Week: Practice your breathing and relaxation exercises.

Week 32

Baby: Your baby measures about 18.9 inches long from head to toe and weighs almost 4 pounds. It fills almost all the space in your uterus now, either lying with the head up or sometimes still with enough room to do somersaults. A layer of fat is forming underneath the thin, wrinkly skin. Baby's practicing opening his eyes and breathing.

Mom-to-be: Although you've only been seeing the doctor monthly, now you'll probably start seeing your practitioner every two weeks until the last month, when you'll probably switch to weekly visits. You may continue to get backaches and leg cramps. You may also notice colostrum leaking from your breasts, a yellowish fluid that precedes milk production.

Tip of the Week: You might be carrying differently from others at the same stage of pregnancy. Whether you're carrying higher or lower, bigger or smaller, wider or more compact depends on the size and position of baby, your body type and how much weight you've gained. For more comfort, drink plenty of fluids, elevate your legs when sitting, lie on your left side and wear support stockings.

Week 33

Baby: Your baby measures about 19.4 inches from head to toe and weighs about 4.4 pounds. The next few weeks will mark lots of growth in the baby. The fetus will gain more than half its birth weight in the next seven weeks. Baby begins to move less now as it runs out of room and curls up with knees bent, chin resting on chest and arms and legs crossed.

Mom-to-be: The uterus is about 5.2 inches above your navel, and you've gained between 22 and 28 pounds. Of the pound a week you're gaining now, roughly half is going to your baby.

Tip of the Week: It's medically safe to continue having sex with your partner, but you may be too uncomfortable. Talk with your spouse about other ways to remain intimate, including backrubs and foot massages.

Week 34

Baby: Your baby measures about 19.8 inches from head to toe and weighs about 5 pounds. Baby is probably settling into the head-down position, although it might not be final. Organs are now almost fully mature, except for lungs, and the skin is pink instead of red. Fingernails reach the ends of fingers, but toenails are not yet fully grown. Baby might have lots of hair. Movements are less frequent because of the tight fit.

Mom-to-be: Your uterus hardens and contracts as practice for labor, known as Braxton Hicks contractions, but you may not feel them yet. Your pelvis has expanded and may ache, especially at the back. The uterus is pushed hard against your lower ribs and your rib cage may be sore, and your navel is probably pushing out as a result of your abdomen being stretched.

Tip of the Week: Start thinking about whether you want to breast-feed, which helps increase your child's immunities. You may want to consult a lactation expert or the La Leche League, an organization that encourages and promotes breast-feeding, or simply talk with friends or relatives who can share their experiences.

What's Happening Inside You?

By the end of these four weeks, your baby will weigh as much as 5 pounds. Your baby continues to mature and develop reserves of body fat. You may notice that your baby is kicking more. Baby's brain is developing rapidly at this time, and he or she can hear. Most internal systems are well developed, but the lungs may still be immature.

Symptoms of pregnancy in each week (26 to 30)

Week 26

Baby: Your baby measures about 9.2 inches from crown to rump and weighs almost 2 pounds now. Its hearing is fully developed. As the fetus reacts to sounds, its pulse increases. Your baby will even move in rhythm to music. Lungs are still growing but are not yet mature. Patterns of your baby's brain waves appear like a full-term newborn. It also has patterns of sleeping and waking.

Mom-to-be: The baby's constant movements should be reassuring. You'll be putting on weight at the rate of about 1 pound per week now. You may be feeling some rib pain as your baby grows and pushes upward on your rib cage. The pressure may also be causing indigestion and heartburn. You may even be feeling stitch-like pains down the sides of your abdomen as your uterine muscle stretches.

Tip of the Week: If you're planning to return to work, you might want to begin checking out the availability of child care in your area. Nannies cost about $250 to $600 per week, group day care typically ranges from $100 to $200 per week, and home day care runs from about $75 to $125 per week. But keep in mind that you might change your mind after your baby arrives.

Week 27

Baby: Your baby measures about 9.6 inches from crown to rump and weighs a little more than 2 pounds. Hands are active and muscle coordination is such that he can get his thumb into his mouth. Thumb-sucking calms the baby and strengthens his cheek and jaw muscles. Your baby can cry now.

Mom-to-be: You may see stretch marks as your uterus continues to expand. Most women have gained about 16 to 22 pounds by now. Balance and mobility also may be changing as you grow larger.

Tip of the Week: During your last trimester you should talk to your doctor or midwife about the delivery. You'll learn such things as signs to predict labor and how far apart the contractions should be before going to the hospital or birth center. It's also the time to begin interviewing pediatricians and to take care of other logistics, like pre-registration and a birthing plan (what you envision your labor and delivery will be like). This plan should be written in your patient record or attached to it in the form of a birth plan.

Week 28

Baby: Your baby measures about 10 inches from crown to rump, or a total length of about 15.75 inches from head to toe, and weighs about 2.4 pounds. Brain waves show rapid eye movement (REM) sleep, which means your baby may be dreaming. Eyelids are opening. Branches of lungs are developing, so there's a good chance that baby would survive if born prematurely now.

Mom-to-be: Your uterus extends well above your navel. As baby gets bigger and stronger this month, you may be experiencing leg cramps and mild swelling of ankles and feet, difficulty sleeping, shortness of breath, lower abdominal achiness, clumsiness or scattered Braxton Hicks contractions (hardening and relaxing of the uterus, like rehearsals for labor). You may also be urinating more frequently again as the uterus continues to push on your bladder.

Tip of the Week: Even if your partner is planning on being with you in the delivery room, you might want to consider hiring a doula -- a professional labor assistant who provides support, but not medical aid, for the mother and her partner. Studies show that doulas can shorten a woman's labor and reduce the likelihood of needing pain medication, forceps deliveries or a Caesarean section.

Week 29

Baby: Your baby measures about 10.4 inches from crown to rump, or a total length of about 16.7 inches from head to toe, and weighs about 2.7 pounds. At this stage a fetus's eyes are almost always blue and can distinguish bright sunlight or artificial light through the uterine wall. Baby is performing fewer acrobatics as conditions in the womb become more cramped, but still doing a lot of kicking and stretching.

Mom-to-be: Your uterus is about 3.5 to 4 inches above your navel. Weight gain is probably between 19 and 25 pounds. As odds improve that baby could survive outside the womb -- although in a neonatal intensive-care unit -- you may be feeling relieved and excited, or anxious about motherhood, your baby's health, and labor and delivery. If you do experience premature labor, signs include menstrual-like cramps or lower back pain, a trickle of amniotic fluid, or a watery pinkish or brownish discharge preceded sometimes by the passage of a thick, gelatinous mucus plug. Your practitioner often can stop labor from progressing with bed rest, muscle relaxants or other drugs, possibly requiring hospitalization.

Tip of the Week: Your blood pressure typically may rise a little around the seventh month, but contact your practitioner if you get severe headaches, blurred vision or severe swelling of hands, feet or ankles, or if you experience severe weight gain. These symptoms could signal the beginning of preeclampsia, a dangerous condition marked by high blood pressure and high levels of protein in the urine during pregnancy.

Week 30

Baby: Your baby measures about 17 inches from head to toe and weighs about 3 pounds. Baby is growing plumper and beginning to control its own body temperature. Eyebrows and eyelashes are fully developed, and hair on the head is getting thicker. Head and body are now proportioned like a newborn's. Hands are now fully formed and fingernails are growing.

Mom-to-be: Your uterus is about four inches above your navel, and it's hard to believe you still have about 10 weeks to go as baby continues to push on your ribs. You may be feeling more discomfort in your pelvis and abdomen. You'll probably be gaining about a pound a week.

Tip of the Week: The membranes around the baby that contain the amniotic fluid are called the bag of waters. They usually do not break until just before the onset of labor, but if it does break prematurely, your risk of infection increases so call your practitioner immediately.

What's Happening Inside You?

At the end of the seventh month, fat begins to be deposited on your baby. Your baby is about 14 inches long and weighs from 2 to 4 pounds. Your baby's hearing is fully developed and he or she changes position frequently and responds to stimuli, including sound, pain and light.

The amniotic fluid begins to diminish.

If born prematurely, your baby would likely survive after the seventh month but may have some disabilities.

Symptoms of pregnancy in each week (21 to 25)

Week 21 pregnant

Baby: Your baby measures about 7.2 inches from crown to rump and weighs about 10.5 ounces. The fetus is steadily gaining fat to keep warm. Growth rate is slowing down but organ systems, like digestion, are continuing to mature. A waxy film, called the vernix caseosa, is being produced by your baby's oil glands and covers the skin to keep it supple in the amniotic fluid. Buds for permanent teeth are beginning to form.

Mom-to-be: Friends, relatives, even strangers can probably tell you're pregnant by now. Your uterus is starting to extend above your navel. You've probably gained between 10 and 14 pounds by now.

Tip for the Week: Start looking into childbirth classes if you haven't already.

Week 22 pregnant

Baby: Your baby measures about 7.6 inches and weighs about 12.3 ounces. The muscles are getting stronger every week now, and the eyelids and eyebrows are developed. Your baby's acrobatics are pretty constant, and since he responds to sound, rhythm and melody, you can try singing and talking to him. After he's born, the same sounds will soothe him.

Mom-to-be: Your uterus is continuing to grow, but you're probably feeling pretty good -- no more morning sickness, and your abdomen isn't so large that it's getting in the way very much. You may still be getting leg and foot cramps, as well as mild swelling of ankles and feet.

Tip for the Week: To reduce cramping, increase your intake of calcium and potassium. Have a glass of milk before bedtime or snack on potassium-rich foods, such as grapefruits, oranges and bananas. If you do get a leg cramp, try forcing your toes back toward your face and pushing down on the knee to straighten your leg.

Week 23 pregnant

Baby: Your baby is about 8 inches from crown to rump and weighs almost 1 pound. The body is becoming proportioned more like a newborn, but skin is still wrinkled because your baby still has more weight to gain. Lanugo hair on the body sometimes turns darker.

Mom-to-be: Your round belly is definitely noticeable by now. Weight gain will be about 12 to 15 pounds. Vaginal secretions that are typically clear-to-yellowish with a faint smell increase during pregnancy. Check with your practitioner if the color or odor changes significantly since it could signal an infection. You may still have aches in the small of your back. Lying down, massages and applying a heating pad or hot water bottle to the area can help.

Tip of the Week: As your skin continues to stretch, it may become dry and itchy. Keeping it moist with lotions or cream can help reduce these symptoms.

Week 24 pregnant

Baby: Your baby, now about in its 22nd week of development, is 8.4 inches from crown to rump and weighs about 1.2 pounds. It is starting to produce white blood cells, mostly for combating disease and infection, and may respond to your touch or sounds. If you haven't felt hiccups yet, you might feel some jerking motion now.

Mom-to-be: Your uterus is about 1.5 to 2 inches above your navel. Expect to gain about a pound per week this month. Glucose screens for detecting gestational diabetes are given between this week and 28 weeks.

Tip of the Week: Dad-to-be might be able to hear the baby's heartbeat by putting his ear to your abdomen.

Week 25 pregnant

Baby: Your developing baby now measures about 8.8 inches from crown to rump and weighs 1.5 pounds. Skin now becomes opaque instead of transparent. Its body is still covered with folds like a puppy dog that need to grow into its skin. Heartbeat can be heard through a stethoscope or, depending on the position of the baby, by others putting an ear against your belly.

Mom-to-be: Besides your uterus growing upward, it may be getting bigger on the sides of your abdomen. You may be experiencing hemorrhoids, which are dilated blood vessels in the rectal area caused by increased blood flow, constipation, indigestion and heartburn.

Tip of the Week: To soothe hemorrhoids, apply an ice pack or witch hazel, or try a sitz bath (soaking your bottom in shallow warm water) or over-the-counter suppositories and/or medicated wipes such as Tucks. Don't take laxatives or mineral oil.

What's Happening Inside You?

By the end of the sixth month, your baby is about 12 inches long and weighs about 2 pounds. His or her skin is reddish in color, wrinkled, and veins are visible through the baby's translucent skin. Baby's finger and toe prints are visible. The eyelids begin to part and the eyes open.

Your baby may respond to sounds by moving or increasing the pulse, and you may notice jerking motions if baby hiccups.

If born prematurely, your baby may survive after the 23rd week with intensive care.

Symptoms of pregnancy in each week (17 to 20)

Week 17 pregnant

Baby:Your baby, now about in its 15th week of development, measures about 4.4 to 4.8 inches from crown to rump and has doubled in weight in the last two weeks to about 3.5 ounces. Fat begins to form, helping your baby's heat production and metabolism. The lungs are beginning to exhale amniotic fluid, and the circulatory and urinary systems are working. Hair on head, eyebrows and eyelashes is filling in.

Mom-to-be: You're showing more now, with an obvious swelling in your lower abdomen. A five- to 10-pound weight gain is typical by now. You also may be noticing an increase in appetite.

Tip of the Week: Change positions slowly, especially when you move from a lying down position to sitting or from a sitting position to standing to avoid feeling dizzy or faint. If you feel lightheaded, sit down and lower your head, or lie down for a moment.

Week 18 pregnant

Baby: Your baby measures 5 to 5.6 inches from crown to rump and weighs about 5.25 ounces. The rapid growth spurt is tapering off, but reflexes are kicking in. It can yawn, stretch and make facial expressions, even frown. Taste buds are beginning to develop and can distinguish sweet from bitter tastes. The baby will suck if its lips are stroked and it can swallow, and even get the hiccups. The retinas have become sensitive to light, so if a bright light is shined on your abdomen, baby will probably move to shield its eyes.

Mom-to-be: Your uterus, about the size of a cantaloupe, can probably be felt just below your navel. You're most likely feeling the baby move by now. A mid-pregnancy ultrasound may be performed between now and 22 weeks to assess fetal growth and development and to verify the due date. If the baby is in the right position, the ultrasound may even be able to determine whether it's a boy or a girl. Your heart has to work 40 percent to 50 percent harder now to support your pregnancy.

Tip for the Week: Suggest that your partner go with you for the ultrasound. It's a chance to catch the first glimpse of your baby together, as well as provide a snapshot to show friends and family later. Sonograms still don't guarantee a healthy baby, but they can provide reassurance and spot some problems.

Week 19 pregnant

Baby: Your baby measures about 5.2 to 6 inches from crown to rump and weighs about 7 ounces. Skin is developing and transparent, appearing red because blood vessels are visible through it. Creamy white protective coating, called vernix, begins to develop.

Mom-to-be: As your baby continues to grow, you may be feeling some mid-pregnancy aches and pains by now -- lower abdominal achiness, dizziness, heartburn, constipation, leg cramps, mild swelling of ankles and feet, and a backache. Dilated blood vessels might cause tiny, temporary red marks (called spider nevi) on your face, shoulders and arms.

Tip of the Week: Take care not to get overtired since rapid growth of the baby can compound the burden on your heart, lungs and kidneys.

Week 20 pregnant

Baby: The fetus measures about 5.6 to 6.4 inches from crown to rump and weighs about 9 ounces. Your baby can hear sounds by now -- your voice, heart and your stomach growling, as well as sounds outside your body. It will cover its ears with its hands if a loud sound is made near you, and it may even become startled and "jump." The baby is moving often, too -- twisting, turning, wiggling, punching and kicking.

Mom-to-be: Congratulations! You're at about the midpoint of your pregnancy. Your uterus is just about even with your navel. Your waistline has pretty much disappeared, but only temporarily! The risk of bladder infections increases because the smooth muscles in the urinary tract relax. Your breathing will become deeper and you may perspire more than usual from a more active thyroid gland.

Tip of the Week: To alleviate backaches, maintain good posture. Sit with a footstool or use an ergonomic chair at the office, avoid standing for too long, sleep with a small pillow under your side at the waist, and lift things with your legs instead of your back.

What's Happening Inside You?

Hair is beginning to grow on your baby's head and lanugo, a soft fine hair, covers his or her shoulders, back, and temples. This hair protects your baby and is usually shed at the end of the baby's first week of life.

Your baby's skin is covered with a whitish coating called vernix caseosa. This "cheesy" substance, thought to protect baby's skin from long exposure to the amniotic fluid, is shed just before birth.

You may begin to feel your baby move, since he or she is developing muscles and exercising them. This first movement is called quickening.

By the end of the fifth month, your baby is about 10 inches long and weighs from 1/2 to 1 pound.

Symptoms of pregnancy in each week (13 to 16)

Week 13 pregnant

Baby: Your fully formed fetus, now in about its 11th week of development, measures 2.6 to 3.1 inches from crown to rump and weighs between half an ounce and seven-tenths of an ounce -- about the size of a peach. The head is still disproportionately bigger than the body, but the rest of the body is starting to catch up. In fact, your baby is growing rapidly these days. The face is starting to look more human, with eyes moving closer together. Toes and fingers are clearly separate, and ankles and wrists have formed. External genitalia are becoming visible. Intestines are shifting into their proper place, too.

Mom-to-be: Your uterus has grown a lot. It's filling your pelvis now and starting to grow upward into your abdomen. It probably feels like a soft, smooth ball. If you haven't put on any weight yet because of morning sickness, you'll begin to now as you start to feel better.

Tip for the Week: It's easy for your partner to feel left out of the pregnancy since he isn't feeling the same physical changes that you are. Both of you should share your excitement about having a child, your dreams, worries and your partner's level of involvement. Suggest that your partner goes to a check-up with you to hear the baby's heartbeat.

Week 14 pregnant

Baby: Your baby measures about 3.2 to 4.1 inches from crown to rump now and weighs almost an ounce. The ears are shifting from the neck to the sides of the head, and the neck is getting longer and chin more prominent. Facial features and unique fingerprints are all there. Your baby is beginning to respond to outside stimuli. If your abdomen is poked, the fetus will try to wriggle away.

Mom-to-be: You're probably wearing maternity clothes now. Your skin and muscles are starting to stretch to accommodate your growing baby. You may notice some constipation because pregnancy hormones relax the bowel.

Tip of the Week: Try to alleviate constipation with moderate exercise, and by drinking plenty of fluids and eating lots of fruit and vegetables, preferably raw.

Week 15 pregnant

Baby: Your 13-week-old fetus now measures about 4.1 to 4.5 inches from crown to rump and weighs about 1.75 ounces. Its body is covered by an ultrafine hair, called lanugo, which is usually shed by birth. Eyebrows and hair on the top of the head are beginning to grow. He may even be sucking his thumb by now. Bones are getting harder.

Mom-to-be: Your uterus can probably be felt about 3 to 4 inches below your navel. Sometime in the next five weeks you'll be offered a quadruple marker screening test, which measures four chemicals in your blood -- alpha-fetoprotein (AFP), human chorionic gonadotropin (hCG), inhibin A, and estrogen produced by the placenta. The test is a more accurate predictor of Down syndrome than AFP testing alone. Amniocentesis, which tests a small sample of amniotic fluid withdrawn by an ultrasound-guided needle, is usually performed between now and 18 weeks. It may be recommended if you're 35 or older or if your AFP or quadruple marker screen test results were suspicious.

Tip of the Week: Start learning to sleep on your left side because circulation is best that way. Lying on your back or stomach after about the fourth or fifth month can put extra pressure on your growing uterus and decrease circulation to your baby. You can try tucking pillows behind you and between your legs. Some manufacturers make a pregnancy pillow that supports your entire body.

Week 16 pregnant

Baby: Your baby now measures about 4.3 to 4.6 inches from crown to rump and weighs about 2.8 ounces. Fingernails are well-formed and the fine hair, lanugo, may be growing on the head. Arms and legs are moving. The nervous system is functioning and muscles are responding to stimulation from your baby's brain. You may be able to hear the baby's heartbeat in the doctor's office.

Mom-to-be: Your uterus has grown significantly by now and weighs about 8.75 ounces. Within the next few weeks you may start to feel your baby move, called "quickening." It's often like a gas bubble or subtle fluttering movement. As it happens more regularly, you'll know it's your baby. There are other physiological changes happening in your body. Increased blood volume to support your growing fetus may produce nosebleeds, and leg veins may become more apparent. Your uterus is shifting so you may not have to urinate so much.

Tip of the Week: If veins in your legs are beginning to bulge, you may want to use support stockings, elevate your feet when you can and exercise to improve blood flow.

What's Happening Inside You?

Your baby's fingers and toes are well-defined; eyelids, eyebrows, eyelashes, nails and hair are formed. Teeth and bones become denser. Your baby can even suck his or her thumb, yawn, stretch and make faces.

The nervous system is starting to function. The reproductive organs and genitalia are now fully developed, and your health care provider can see on ultrasound if you are having a boy or a girl. Your baby's heartbeat may now be audible through an instrument called a Doppler.

By the end of the fourth month, your baby is about 6 inches long and weighs about 4 ounces.

Symptoms of pregnancy in each week (9 to 12)

9 Weeks Pregnant

Baby: The embryo measures about 0.9 inches to 1.2 inches from crown to rump, or the size of a strawberry. The arms and legs are longer, and the fingers might be a little swollen where the touch pads are forming. The head is more erect and neck is more developed. Your baby now moves its body and limbs, and this movement can be visible during an ultrasound, but you won't be able to feel it yet.

Mom-to-be: Your uterus is continuing to grow, and you may begin to see your waistline thickening. But unless you tell people the good news, your pregnancy still won't be noticeable to others. Weight gain is still small, if at all, since you could be experiencing food aversions, cravings, heartburn, indigestion, nausea and bloating. Mood swings and weepiness similar to PMS symptoms are common, too.

Tip for the Week: Eat plenty of foods that contain calcium -- such as cheeses, sardines and broccoli -- to provide sufficient calcium for the development of your baby's teeth and bones.

10 Weeks Pregnant

Baby: Congratulations! Your baby is now officially called a "fetus." It looks a little like a medium shrimp, measuring 1.25 to 1.68 inches from crown to rump, and weighing a little less than two-tenths of an ounce. You might be reassured to know that most physical malformations have occurred by the end of this week. But other developmental processes, such as those affecting behavior and intelligence, will continue throughout pregnancy. Eyes are covered by skin that will eventually split to form eyelids.


Mom-to-be: You still probably don't show much physically, but you may be wearing looser clothes. You may even be starting to eye maternity clothes, although you probably still don't need them. You may continue to feel tired and moody, but take heart: These symptoms shouldn't last too much longer.

Tip of the Week: If you're going to have chorionic villus sampling (CVS), a prenatal test used to detect genetic defects such as Tay-Sachs, sickle cell anemia, most types of cystic fibrosis and Down syndrome, it will probably be scheduled between now and 12 weeks.

11 Weeks Pregnant

Baby: Your fetus, about the size of a large lime, measures about 1.75 to 2.4 inches from crown to rump and weighs about three-tenths of an ounce. About now the rapid "swooshing" noises of the heartbeat can be heard through a Doppler sound-wave stethoscope. Fingernails and external genitalia are showing distinguishing characteristics, and the baby is swallowing and kicking, although you still won't feel it.

Mom-to-be: Your uterus is almost big enough to fill your pelvis and may be felt in your lower abdomen. You may also experience changes in hair, skin, fingernails or toenails.


Tip of the Week: Don't ignore your dental hygiene during pregnancy. Floss and brush regularly, and make sure you see your dentist at least once in these nine months. Your gums may bleed more because of pregnancy hormones and increased blood volume.

12 Weeks Pregnant

Baby: The fetus now measures about 2.5 inches from crown to rump and weighs between three-tenths of an ounce and half an ounce. It is fully formed, from tooth buds to toenails, and your baby's job now is to continue getting larger and stronger for the rest of your pregnancy. With the most critical development behind the fetus, the chance of miscarriage drops considerably after this week.

Mom-to-be: Nausea and energy start to improve. You may be experiencing occasional headaches, dizziness and fatigue from hormonal changes. If it's your first baby, you still could be wearing loose-fitting clothes, but if you've had other pregnancies, you'll probably start to show earlier and may be in maternity clothes. The typical weight gain by now is about three to five pounds. Fathers-to-be might also experience pregnancy symptoms, called couvade, or "hatching," during the third month and at delivery, including nausea, abdominal pain, appetite changes and weight gain.

Tip of the Week: Most women develop stretch marks on their abdomen, breasts, hips or buttocks sometime during their pregnancy. They won't go away, but they'll usually fade after pregnancy. Despite claims from manufacturers, creams and oils don't minimize them. It depends on your skin's natural elasticity. Gradual rather than rapid weight gain may help, as well as avoiding excessive weight gain during pregnancy.

What's Happening Inside You?

By the end of the third month, your baby is fully formed. Your baby has arms, hands, fingers, feet and toes and can open and close its fists and mouth. Fingernails and toenails are beginning to develop and the external ears are formed. The beginnings of teeth are forming. Your baby's reproductive organs also develop, but the baby's gender is difficult to distinguish on ultrasound. The circulatory and urinary systems are working and the liver produces bile.

At the end of the third month, your baby is about 4 inches long and weighs about 1 ounce.
