Pregnancy: pregnancy week by week

Pregnancy week 39, third trimester. Your may already be in position for delivery. Your to-do list runs long, but be sure to enjoy your last few weeks of freedom.

Pregnancy week 37, trimester 3. In the 37th week, you're ready to get this show on the road. Your doctor or midwife will check to see if your cervix has begun to thin out and dilate and how far the baby has descended.

Pregnancy week 35, third trimester. Ever notice a few drops of clear or yellowish fluid on your nipples? This "early milk," called colostrum, is loaded with your system's antibodies and is the perfect food for your baby during his first few days.

Pregnancy week 33, third trimester. You're putting on a pound a week now, but eating isn't as enjoyable as it once was.

Pregnancy week 31, third trimester. Pressure from your increasingly heavy uterus is funneling blood and other fluids to your legs, resulting in swollen feet.

Pregnancy week 28, third trimester. You've probably gained 17 to 24 pounds. Your uterus has moved to three inches above your navel and is pressing against the tubes between the kidneys and bladder, slowing the flow of urine.

Pregnancy week 26, second trimester. With two weeks left of the second trimester, your back hurts, your legs are cramping up, and your pelvic area feels heavy.

Pregnancy week 24, second trimester. Faint red stretch marks may begin to stretch across your abdomen, hips and breasts now that your uterus has risen to two inches above your belly button.

Pregnancy week 22, second trimester. You might be craving citrus or sugary foods, or develop an aversion to foods you once loved.
