Vaginal bleeding in pregnancy is any discharge of blood from the vagina during pregnancy.
Up to 1 in 4 women have vaginal bleeding at some time during their pregnancy. Bleeding is more commonin the first 3 months (first trimester), especially with twins.
During the first 3 months, vaginal bleeding may be a sign of a miscarriage or ectopic pregnancy. Contact the doctor right away.
During months 4 - 9, bleeding may be a sign of:
- The placenta separating from the inner wall of the uterus before the baby is born (abruptio placentae)
- The placenta is covering all or part of the opening to the cervix (placenta previa)
- Vasa previa
Other possible causes of vaginal bleeding during pregnancy:
Avoid sexual intercourse until your health care provider tells you that it is safe to start having intercourse again.
Drink only fluids if the bleeding and cramping are severe.
You may need to cut down your activity or be put on bed rest at home.
- Bed rest at home may be for the rest of your pregnancy or until the bleeding stops.
- The bed rest may be complete.
- Or, you may be able to get up to go to the bathroom, walk around the house, or do light chores.
Medication is not needed in most cases. Do not take any medicines without talking to your health care provider.
Talk to your doctor about what to look for, such as the amount of bleeding and color of the blood.
