I'm not a doctor, and I don't play one on TV (although I did play Dr. Watson once in a community theater production of Hound of the Baskervilles, but that is irrelevant) but I would just not try that if I were you if you don't want to get pregnant.

I'm certain that oral pills are designed to break down in your stomach and distribute into your system through your digestive tract. I wouldn't trust the hormones in the pill to distribute properly dissolving in your vagina. I just don't think it's supposed to work that way.

Maybe one of the nurses here can shed some light.
