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.

17 Weeks Pregnant

Try not to get freaked out by the numbers on your scale. At 17 weeks, baby’s working on getting stronger, and your body’s working on getting bigger. That means putting on some pounds and -- we hate to break it to you -- getting some stretch marks. Make sure you document your growing bump by taking lots of photos. Sure, you might not always feel so pretty, but one day you’re going to look back at pregnancy and reminisce (really -- we promise). You’ll also want to start figuring out some plans, like whether or not you’re going to find out baby’s gender (you should be able to soon!), and what kind of childbirth class you’d like to take. As you start making these decisions, the pregnancy will feel even more real, which is probably super exciting, but part of you is probably feeling a little nervous. After all, you’re at week 17; that’s almost halfway there and there’s still a lot left to do. Chill! You’ll get it done. Just remember not to try to do it all yourself -- ask for help!

your baby's the size of an onion!
Baby continues to beef up. Now she's about 5.1 inches long and weighs about 5.9 ounces.

your baby at 17 weeks
  • Her rubbery cartilage is now turning to bone.
  • And she's growing some meat on those bones -- putting on some fat.
  • She's growing a stronger, thicker umbilical cord, too.

pregnancy symptoms at 17 weeks
  • Vaginal discharge, sweat, mucus and more bodily fluids. They're in full force, because of your increased blood flow.
  • Weird dreams. This might be hormonal, but it might also be the result of your nerves and anticipation.
  • Itchy boobs and bump -- as they're growing, your skin is stretching thinner.
  • Rapid weight gain. You've probably gained about five to 10 pounds by now.
