Week 31

This week, your baby measures over 16 inches long. He weighs about 3.3 pounds (try carrying four navel oranges) and is heading into a growth spurt. He can turn his head from side to side, and his arms, legs, and body are beginning to plump out as needed fat accumulates underneath his skin. He's probably moving a lot, too, so you may have trouble sleeping because your baby's kicks and somersaults keep you up. Take comfort: All this moving is a sign that your baby is active and healthy.

How your life's changing:

Have you noticed the muscles in your uterus tightening now and then? Many women feel these random contractions — called Braxton Hicks contractions — in the second half of pregnancy. Often lasting about 30 seconds, they're irregular, and at this point, they should be infrequent and painless. Frequent contractions, on the other hand — even those that don't hurt — may be a sign of preterm labor. Call your practitioner immediately if you have more than four contractions in an hour or any other signs of preterm labor: an increase in vaginal discharge or a change in the type of discharge (if it becomes watery, mucus-like, or bloody — even if it's pink or just tinged with blood); abdominal pain or menstrual-like cramping; an increase in pressure in the pelvic area; or low back pain, especially if you didn't have it before.

You may have noticed some leaking of colostrum, or "premilk," from your breasts lately. If so, try tucking some nursing pads into your bra to protect your clothes. (And if not, it's certainly nothing to worry about; your breasts are making colostrum all the same, even if you don't see any.) If your current bra is too snug, you might also want to pick up a nursing bra. Choose a nursing bra at least one cup size bigger than you need now. When your milk comes in you'll be grateful for that extra room!

If you're having a boy, you and your partner will want to take some time to think about whether or not to have your baby circumcised. Find out the pros and cons from your doctor, and what the procedure involves.

This Week's Activity:

You don't need to pack your bag yet, but start making a list of items to bring to the hospital. Besides a change of clothes and a toothbrush, some items to include:
• A photograph or object to focus on during labor
• Snacks to keep your energy up and gum or mints for bad breath
• Cozy socks and slippers
• Your favorite pillow
• Some light reading material
• A nursing nightie and nursing bra
• A going-home outfit for your baby
• A camera or camcorder, fresh batteries, and film, if necessary

Week 30!!

How your baby's growing:

Your baby's about 15.7 inches long now, and she weighs almost 3 pounds (like a head of cabbage). A pint and a half of amniotic fluid surrounds her, but that volume will decrease as she gets bigger and takes up more room in your uterus. Her eyesight continues to develop, though it's not very keen; even after she's born, she'll keep her eyes closed for a good part of the day. When she does open them, she'll respond to changes in light but will have 20/400 vision — which means she can only make out objects a few inches from her face. (Normal adult vision is 20/20.)

How your life's changing:

You may be feeling a little tired these days, especially if you're having trouble sleeping. You might also feel clumsier than normal, which is perfectly understandable. Not only are you heavier, but the concentration of weight in your pregnant belly causes a shift in your center of gravity. Plus, thanks to hormonal changes, your ligaments are more lax, so your joints are looser, which may also contribute to your balance being a bit off. Also, this relaxation of your ligaments can actually cause your feet to spread permanently, so you may have to invest in some new shoes in a bigger size.

Remember those mood swings you had earlier in pregnancy? The combination of uncomfortable symptoms and hormonal changes can result in a return of those emotional ups and downs. It's normal to worry about what your labor will be like or whether you'll be a good parent. But if you can't shake the blues or feel increasingly irritable or agitated, talk to your doctor or midwife. You may be among the 1 in 10 expectant women who battle depression during pregnancy. Also let your caregiver know if you're frequently nervous or anxious.

Week 29

How your baby's growing:

Your baby now weighs about 2 1/2 pounds (like a butternut squash) and is a tad over 15 inches long from head to heel. His muscles and lungs are continuing to mature, and his head is growing bigger to make room for his developing brain. To meet his increasing nutritional demands, you'll need plenty of protein, vitamins C, folic acid, and iron. And because his bones are soaking up lots of calcium, be sure to drink your milk (or find another good source of calcium, such as cheese, yogurt, or enriched orange juice). This trimester, about 250 milligrams of calcium are deposited in your baby's hardening skeleton each day.

How your life's changing:

Your baby's very active now. Your practitioner may ask you to spend some time each day counting kicks and will give you specific instructions on how to do this. Let her know if you ever notice a decrease in activity. You may need a nonstress test or biophysical profile to check on your baby's condition.

Some old friends — heartburn and constipation — may take center stage now. The pregnancy hormone progesterone relaxes smooth muscle tissue throughout your body, including your gastrointestinal tract. This relaxation, coupled with the crowding in your abdomen, slows digestion, which in turn can cause gas and heartburn — especially after a big meal — and contribute to constipation as well.

Your growing uterus may also be contributing to hemorrhoids. These swollen blood vessels in your rectal area are common during pregnancy and usually clear up in the weeks after giving birth. If they're itchy or painful, try soaking in a sitz bath or applying cold compresses medicated with witch hazel to the affected area. Also avoid sitting or standing for long stretches. Talk with your practitioner before using any over-the counter remedies during pregnancy, and let her know if you have any rectal bleeding. To prevent constipation, eat a high-fiber diet, drink plenty of water, and get some regular exercise.

Some women get something called "supine hypotensive syndrome" during pregnancy, where laying flat on your back causes a change in heart rate and blood pressure that makes you feel dizzy until you change position. You might note that you feel lightheaded if you stand up too quickly, too. To avoid "the spins" lie on your side rather than your back, and move slowly as you go from lying down to sitting and then standing.

28 Weeks. 3rd Trimester!

How your baby's growing:

By this week, your baby weighs two and a quarter pounds (like a Chinese cabbage) and measures 14.8 inches from the top of her head to her heels. She can blink her eyes, which now sport lashes. With her eyesight developing, she may be able to see the light that filters in through your womb. She's also developing billions of neurons in her brain and adding more body fat in preparation for life in the outside world.

How your life's changing:

You're in the home stretch! The third and final trimester starts this week. If you're like most women, you'll gain about 11 pounds this trimester.

At this point, you'll likely visit your doctor or midwife every two weeks. Then, at 36 weeks, you'll switch to weekly visits. Depending on your risk factors, your practitioner may recommend repeating blood tests for HIV and syphilis now, as well as doing cultures for chlamydia and gonorrhea, to be certain of your status before delivery. Also, if your glucose screening test result was high and you haven't yet had follow-up testing, you'll soon be given the 3-hour glucose tolerance test. And if the blood work done at your first prenatal visit showed that you're Rh negative, you'll get an injection of Rh immunoglobulin to prevent your body from developing antibodies that could attack your baby's blood. (If your baby is Rh positive, you'll receive another shot of Rh immunoglobulin after you give birth.)

Around this time, some women feel an unpleasant "creepy-crawly" sensation in their lower legs and an irresistible urge to move them while trying to relax or sleep. If this sensation is at least temporarily relieved when you move, you may have what's known as restless legs syndrome (RLS). No one knows for sure what causes RLS, but it's relatively common among expectant mothers. Try stretching or massaging your legs, and cut down on caffeine, which can make the symptoms worse. Ask your caregiver if you should try iron supplements, which can sometimes relieve RLS.

Week 27.

How your baby's growing:

This week, your baby weighs almost 2 pounds (like a head of cauliflower) and is about 14 1/2 inches long with her legs extended. She's sleeping and waking at regular intervals, opening and closing her eyes, and perhaps even sucking her fingers. With more brain tissue developing, your baby's brain is very active now. While her lungs are still immature, they would be capable of functioning — with a lot of medical help — if she were to be born now. Chalk up any tiny rhythmic movements you may be feeling to a case of baby hiccups, which may be common from now on. Each episode usually lasts only a few moments, and they don't bother her, so just relax and enjoy the tickle.

How your life's changing:

The second trimester is drawing to a close, but as your body gears up for the final lap, you may start noticing some new symptoms. Along with an aching back, for example, you may find that your leg muscles cramp up now and then. They're carrying extra weight, after all, and your expanding uterus is putting pressure on the veins that return blood from your legs to your heart as well as on the nerves leading from your trunk to your legs. Unfortunately, the cramps may get worse as your pregnancy progresses. Leg cramps are more common at night but can also happen during the day. When a cramp strikes, stretching the calf muscle should give you some relief. Straighten your leg and then gently flex your toes back toward your shin. Walking for a few minutes or massaging your calf sometimes helps, too.

It may be the furthest thing from your mind right now, but it's not too soon to think about family planning. You'll want to have made some decisions about postpartum birth control before your baby arrives. If you're considering a tubal ligation, be aware that most states require you to sign a consent form at least 30 days beforehand. So if you'd like the option of having the surgery during your postpartum hospital stay, don't wait too much longer to discuss it with your caregiver. (You can still change your mind later.)
