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.

22 Weeks Pregnant

During week 22, baby’s invading your space, which is why it might be tough to catch your breath and why your back might be killing you. Hey, as she grows, she may be expanding your belly so much (so fast) that you might have some stretch marks -- and you might even have a newfound “outtie”! What’s not so cool is that the stretch marks may never fade, but we promise they’ll fade in color after delivery. And your outtie will go back to an innie, we promise. As for sex, all these body changes, along with another fun one -- discharge! -- might be messing with your mojo, but some moms-to-be actually find they have an increase in libido around 22 weeks. That’s because your hormones are pretty much raging at this point. This is also a good time to schedule a maternity portrait session. You’ll want to aim for the third trimester -- but not so late that you risk going into labor before your appointment.

your baby's the size of a papaya!
During month five, the average fetus measures about 10.5 to 11.8 inches and weighs about 12.7 to 20.8 ounces.

  • Now that he's got more developed eyes and lips, he's looking even more like a newborn.
  • He's sleeping in cycles -- about 12 to 14 hours per day (hint: they're probably those times you're not feeling any kicks!).
