If you notice bleeding during pregnancy, it is important not to ignore it, but try not to panic. In early pregnancy, bleeding can happen for reasons like implantation, hormonal changes, or minor irritation. Sometimes, though, it may signal conditions such as a threatened miscarriage or, less often, an ectopic pregnancy. Later in pregnancy, bleeding might be caused by placental problems or changes in the cervix. Because you are pregnant, any bleeding should be checked by a doctor as soon as possible to find out the cause. How much you bleed, whether you have pain, and how far along you are in your pregnancy all help decide how serious it is. Do not take any medicine on your own. Until you see a doctor, rest, avoid heavy activity, and do not have intercourse. If you have heavy bleeding, severe abdominal pain, dizziness, or pass clots, get medical help right away. Getting checked early helps protect you and your baby and ensures you get the right care.
