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. I'm 17 years old, on the Diane pill for 2 years now - to help regulate my period, but I am a virgin.
It's NOT my period, my period only starts in 2 weeks. I'm not stupid. I know what cramps feel like. This is NOTHING compared to that. It's much more severe. It only lasts about 2 minutes.
