Pregnancy Week by Week

Get a window on what’s happening in your pregnancy, week by week. From week four to week 42, your baby is experiencing a miraculous transformation from a clump of cells to a fully formed (and totally cute) newborn. Just imagine, as early as five weeks, your baby is already starting to form major organs (heart, stomach, liver, and kidneys) and systems (digestive, circulatory, nervous). By eight weeks, your raspberry-sized womb-mate is moving her arms and legs. At the beginning of your second trimester (week 14), your wee one is sucking his thumb. By week 28, the first week of the third trimester, baby (now as big as an eggplant) is prepping for breathing, developing his eyesight and packing on pounds in anticipation of life outside the womb. Each week is a new miracle. Less miraculous is how a mom-to-be may feel. Pregnancy Week-by-Week charts your baby’s development but also lets mom know what she might be feeling during each week of her pregnancy. Pregnancy week by Week includes everything mom needs to know to feel a sense of control over her pregnancy. Each week offers a complete guide to what you might feel, your must-do’s, your nice-to do’s, and answers and advice on everything pregnancy-related. Plus each week’s guide offers tips on maintaining a healthy and comfortable pregnancy from strategies on coping with pregnancy symptoms (morning sickness anyone?) to ideas for healthy eating, and pointers on talking to your OB. Let us guide you along your pregnancy, week by week.

39 Weeks Pregnant

Are we there yet? You’re probably feeling like you want to get this baby the heck out of you. We’re not sure, but the impatience and discomfort many moms feel around 39 weeks (and beyond!) might be nature’s way of getting you mentally prepared for delivery. Remember how freaked out you used to be about it? Now, at week 39 you probably don’t care what you have to do, you just don’t want to be pregnant anymore!

Your baby's the size of a watermelon!
Baby keeps growing, despite being so crowded in there. He probably weighs around 6.2 to 9.2 pounds and measures about 18.9 to 20.9 inches.

your baby at 39 weeks
  • He's probably able to flex his limbs now.
  • His brain is still rapidly developing -- he's getting smarter by the week!
  • His nails may extend past his fingertips.

pregnancy symptoms at 39 weeks
  • False labor. Usually these pains start in the front of your body and ease up when you switch positions. You'll know it's real labor when they start at the top of your uterus and become more frequent.
  • Water breaking. Call your doctor if you suspect yours has broken, or if you think you could be leaking amniotic fluid.
  • More heartburn, hemorrhoids, pelvic pressure and trouble catching your breath.
  • The urge to nest. Don't stress though -- you'll never get everything done.

your must-do's
your nice-to-do's
  • Brush up on your newborn care basics
  • Pay attention to baby's movements, and call your doc if anything is out of the ordinary.
  • Go to the movies! You probably won't have the chance for a while after baby's born.
