What to Do if Your Bag of Waters Breaks
What Is My Bag of Waters? The bag of waters—or amniotic sac—is a bag or “membrane filled with fluid that surrounds your baby in your uterus during pregnancy.” The bag of waters is very important to your baby’s health. The fluid protects your baby and gives your baby room to move around. The bag itself protects your baby from infections that may get into your vagina.
