The answer

TeenHealthFX would like to begin by stating that we recommend all sexually active teenagers use [condoms every time they have sexual intercourse. Condoms are the only form of [birth control that protect from [sexually transmitted infections, and should be used in addition to another form of birth control for best protection.

There are several reasons why vaginal bleeding after sexual intercourse may occur, including yet not limited to:

1. Irritation

  • May occur as a result of friction during sex, and/or lack of lubricant

2. Menstruation

3. [Sexually transmitted infection(s)

4. Vaginal dryness

5. More serious causes may include: injury to the uterine lining, cervicitis, cervical polyps, or pelvic inflammatory disease.

Being that TeenHealthFX cannot conduct a proper diagnosis, we suggest scheduling an appointment with your local physician and/or gynecologist in order to identify the cause of bleeding, as well as any recommended treatment options.

If you don't have a doctor and live in northern New Jersey, you can call the [Adolescent/Young Adult Center for Health at 973-971-5199 for an appointment with an adolescent medicine specialist or contact your local teen health center or [Planned Parenthood. A Planned Parenthood [health center is a good option if you have concerns about cost or confidentiality issues. You can also contact your insurance company for a list of in-network providers.
