What is vaginal bleeding?
Vaginal bleeding is when you pass blood from your vagina (birth canal).
Is vaginal bleeding normal?
Sometimes yes and sometimes no. Vaginal bleeding is normal during your monthly period. Your period usually starts every 21 to 35 days (or up to 45 days in teenagers). Bleeding during a period usually lasts for 3 to 7 days. Girls usually get their first period when they are between 10 and 16 years old.
Newborn girls may have a little bit of vaginal bleeding for up to 2 weeks after being born—this is normal too. If the bleeding continues in newborns for more than 2 weeks, they should be seen by a doctor.
When is vaginal bleeding abnormal?
Bleeding is considered abnormal when you bleed:
Before you get your very first period
Between your periods
While you're pregnant
Bleeding during your period may also be considered abnormal if your period:
Lasts more than 7 days
Is very heavy (you use more than 1 or 2 tampons or pads in an hour)
Happens too frequently (starting fewer than 21 days apart)
Happens too infrequently (starting more than 90 days apart)
Is abnormal vaginal bleeding serious?
It can be serious if you have a lot of bleeding. It can also be serious even if there's not much bleeding but the cause is serious (for example, cancer).

What causes abnormal vaginal bleeding?
Common causes of abnormal bleeding depend on how old you are.
Little girls may be hurt or have something stuck in their vagina, like toilet paper or a toy. Girls younger than 8 years old may be starting puberty too early. Sexual abuse can also be a cause of vaginal bleeding.
Girls just starting to have periods or women just ending their periods may have abnormal bleeding because of changes in their hormones. Some girls or women may have an inherited problem with blood clotting.

What will happen when I go to the doctor?
Doctors will ask questions about your vaginal bleeding, other symptoms, and your usual monthly period.
