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.

38 Weeks Pregnant

Yow! If you feel a sort of lightening bolt running up and down your legs (and in your crotch), don’t freak out. At 38 weeks, baby’s probably sitting pretty low in your pelvis, which means he’s bumping into all kinds of nerves down there -- including some pretty sensitive ones you might not know you had. Be on the lookout for signs of labor, including contractions that come on stronger, at more regular intervals, and the “bloody show.” It could happen any day now -- or it might not be for a few weeks. Until then, try to relax.

Your baby's the size of a pumpkin!
Baby is about 18.9 to 20.9 inches long and weighs about 6.2 to 9.2 pounds. Her head is now about the same circumference as her abdomen.

  • She may have about an inch or so of hair already.
  • She's slowly shedding that white goo on her skin (called vernix caseosa) but you might see some of it at birth.
