Vaginal bleeding during pregnancy can occur for a number of reasons. Some are serious and some aren’t. Bleeding can occur at any point during a pregnancy. If there is just a small amount of bleeding, it will usually stop on its own with no impact to you or your baby. Sometimes, though, bleeding can indicate a dangerous situation for the mother and her child. So regardless of the amount of bleeding and when it occurs, it is important that you see your doctor immediately for further assessment.
