- Vaginal bleeding before puberty OR abnormal bleeding after puberty
- Heavy menstrual bleeding after puberty
- Light breakthrough bleeding or spotting in between menstrual cycles after puberty
- Newborn Vaginal Bleeding. Baby girls can have some minor vaginal bleeding. It can start any time from 2-10 days of life. This is normal and called false menses. The cause is the sudden drop-off in the mother's estrogen (a hormone) after birth. The blood-tinged or pink discharge should not last more than 3 or 4 days.
- Before Puberty. Vaginal bleeding (other than newborn) is not normal. Bleeding in this age group needs an exam.
- First Menstrual Period. If over 8 and has signs of puberty, this most likely is her first period. Signs of puberty are breast changes or pubic hair. Most girls do not have their first period until 2 years after puberty begins. Some girls do start during the first stage of puberty.
- After Puberty. Vaginal bleeding is abnormal if it occurs between regular periods. Heavy bleeding is also not normal. Bleeding that is severe or lasts over 7 days should be seen. Bleeding along with signs of severe anemia (such as pale skin, weakness) should also be seen. Teens may have abnormal bleeding during the year after their periods start. This can be normal. It usually doesn't need an urgent exam unless it's heavy or severe.
- Sexually Transmitted Infections (STIs). May cause spotting or blood-tinged discharge.
- Birth Control. Some birth control medicines can cause breakthrough or abnormal bleeding. This most often occurs for the first few months on the medicines.
- Pregnancy. Vaginal bleeding can be a sign of pregnancy. Teens that are having sex should keep this in mind. In early pregnancy, vaginal bleeding can be a sign of serious problems. Causes include miscarriage or an ectopic pregnancy. If in doubt, always do a pregnancy test.
