Sharp pains in the vaginal area?

So i have been experiencing sharp pains in the vaginal area. I say "area" because it's not exactly my vagina, it's just around there. I don't know if it's my pelvic or what? I don't know why I'm getting this? Please help :(

Extra info: I get it every few days. But it has been happening only recently. It lasts for about 2 minutes. I'm 17 years old, on the "Diane" contraceptive pill for 2 years now - to help regulate my period, but I am a virgin.

P.S. I am NOT on my period and this is NOTHING like cramps.
