Your Baby Is Almost Here: Week 35 of Pregnancy to Birth
Your Baby Is Almost Here: Week 35 of Pregnancy to Birth

At long last, you're about to meet your son or daughter! Watch the miraculous journey your baby will go through as he (or she) exits your uterus and enters the world.

Your Changing Body

Less than 5 percent of women give birth on their actual due dates, which means your baby could come a few hours from now or not for another two weeks. But you're probably so attuned to the possibility of labor that every little twinge makes you think "Is this 'It?'" Labor may begin in several ways.

Your Developing Baby

By now your baby has likely reached his birth weight (typically between 6 and 9 pounds) and length (18 to 22 inches from head to toe). He's accumulated enough body fat to stay cozy after he's born, and your placenta continues to supply him with nutrients and antibodies that will help fend off illnesses.

Tip of the Week

Even if you've been imagining for months how your labor will go, chances are it won't go anything like you've planned. For example, your water might break, but if you're not having any contractions, you might need to be induced. Or maybe your labor will progress so fast that there'll be no time for an epidural.

Your Week 39 To-Do List
