10. Things That Will Come Out of Your Body

So you've survived the mood swings and the hemorrhoids, and you think your surprises are over. Guess again — the day you give birth will probably hold the biggest surprises of all.
Only 1 in 10 mothers' water breaks before labor contractions begin. Some women never experience it — a doctor may need to rupture the amniotic sac (if the cervix is already dilated) when they arrive at the hospital. How much water can you expect? For a full-term baby, there are normally about 2.1 to 5.9 cups (500 to 1400 milliliters) of amniotic fluid. Some women may feel an intense urge to urinate that leads to a gush of fluid when their waters break. Others may have only a trickling sensation down their leg because the baby's head acts like a stopper to prevent most of the fluid from leaking out. In any case, amniotic fluid is generally sweet-smelling and pale or colorless and is replaced by your body every three hours, so don't be surprised if you continue to leak fluid, about a cup an hour, until delivery.
Other unexpected things may come out of your body during labor in addition to your baby, blood, and amniotic fluid. Some women experience nausea and vomiting. Others have diarrhea before or during labor, and flatulence (passing gas) is also common. During the pushing phase of labor, you may lose control of your bladder or bowels. A birth plan can be especially helpful in communicating your wishes to your health care providers about how to handle these and other discomforts of labor and delivery.
There are lots of surprises in store for you once you become pregnant — but none sweeter than the way you'll feel once your newborn is in your arms!
