Bleeding can happen during pregnancy for many reasons, some serious, but others not. During the first trimester, minor spotting or light bleeding is actually common. It can occur when the embryo attaches to the uterus, or from cervix changes, or after sex. You may also bleed if you have an infection. More serious causes of bleeding can include miscarriage or an ectopic pregnancy. Later in pregnancy, bleeding can mean a problem with the placenta or early labor.
Call Doctor If:
There is nothing you can do to prevent a miscarriage once bleeding has started, but your doctor may recommend these measures just to be safe.
- Rest as much as you can.
- Don’t have sex until you know the cause of bleeding and your doctor says it’s OK.
- Note how much and how long bleeding occurs and whether you have pain. Wear a pad to monitor how much you are bleeding.
- Avoid exercise and travel.
- Don’t use a tampon or douche.
