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.

37 Weeks Pregnant

Get excited. At 37 weeks, your baby has reached full term. That means he’s developed his most crucial functions. Of course, he’ll get even healthier and stronger over the next few weeks, so don’t get too impatient. Around week 37, many moms-to-be find themselves organizing cupboards and scrubbing their floors. That’s the nesting instinct kicking in as your body senses baby will be here shortly. It also might be your brain’s way of making sure you’re prepared for just about anything, so you can feel like you have an extra edge on this whole new parent thing.

Your baby's the size of a winter melon!
Yay! Baby has reached full term. He likely measures around 18.9 to 20.9 inches and weighs about 6.2 to 9.2 pounds. He's gaining about 1/2 ounce each day.
