Question for Betty.
 

Me and my boyfriend had unprotected sex and he cummed in me and I was ovulating.  I took Plan B right after and I got my period early and it was light but longer.  And last time we had sex I was somewhat bleeding.  I was 16 when I took Plan B.  Can that affect me?

 
Betty's Answer.
 
Your question on whether Plan B may be a cause of concern due to your age, 16. If your question is about future fertility, no, that is not a problem.  My concern is that you may be continuing to have unprotected sex.  The fact that you were bleeding during your most recent sexual intercourse does not protect you from pregnancy. 

I would strongly recommend that you visit a health care provider for assistance with ongoing birth control. Plan B is most effective when taken within 72 hours of unprotected intercourse, but it is not 100% effective.  It is important to begin a more reliable form of birth control, which should include condoms, as you also need protection against Sexually Transmitted Infections. I would also recommend STI screening for you and your partner.
