Vaginal bleeding during pregnancy can be scary. It's common, however, and it isn't always a sign of trouble. Most women who experience vaginal bleeding during pregnancy — particularly during the first trimester (weeks one through 12) — go on to deliver healthy babies.
Still, it's important to take vaginal bleeding during pregnancy seriously. Sometimes vaginal bleeding during pregnancy indicates an impending miscarriage or a condition that needs prompt treatment. By understanding the most common causes of vaginal bleeding during pregnancy, you'll know what to look for — and when to contact your health care provider.
