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.

20 Weeks Pregnant

Congrats! You almost reached the halfway point. Making it to 20 weeks probably feels pretty darn good. After all, your energy’s high and as long as your partner is up for it, things are probably happening between the sheets. Of course, it wouldn’t be pregnancy if you weren’t experiencing some annoying symptoms. Right now, it’s likely swelling, heartburn and leg cramps, but all of that probably feels insignificant now that you’ve got ultrasound photos of your rapidly developing baby. How cute is that nose? If you found out baby’s sex, you’re in a completely new mindset, are we right? Now, those baby names you’re throwing out are more likely to end up as baby’s, and when you find yourself in a baby store, those little blue or pink outfits aren’t just adorable, they’re must-haves. And since now you can add clothes and other boyish or girlish things to your wish list, week 20 is the time you probably want to start putting together your baby registry too. Happy shopping!

your baby's the size of a banana!
Baby weighs about 10.2 ounces and measures about 6.5 inches. She's still got a lot of growing to do though. Can you believe you're halfway done?

  • She's got working taste buds.
  • Now, she's gulping down several ounces of amniotic fluid each day -- that's significantly more than before.
