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.

How will I know when my baby drops?

Everyone keeps telling me to look out for baby “dropping,” but how will I be able to tell?

The Bump Expert

For most of your pregnancy, baby sort of swims around from one side of your uterus to the other. But at the 33- or 34-week mark, he’ll likely start to move permanently into the “head down” position to prep for labor, and descend further into your pelvis. Many women recognize when it happens because there’s an almost immediate sense of relief: The constant pressure on your stomach and lungs might suddenly lift, and you might get a break from heartburn and shortness of breath. It can be a pretty big visual difference for some women too -- you could suddenly go from “carrying high” to having your bump centered much lower in your torso.

When baby drops, you might also feel more discomfort farther down, plus need to make even more frequent trips to the bathroom since the baby’s now taking up more room near your bladder, as well as more pressure in the pelvic area. Once baby’s dropped, it’s a good sign that all systems are ready to go. But know that baby might not actually drop until you’re already in labor.
