Hi, I.ve been very freaked out by the fact that i've had no period these last 8 months. I have not been sexually active in over a year so there is no chance of pregnancy. Also, I don't use any birth control. I don't have insurance so begot I see a doctor I need to ne sure it's necessary, anyways I've always been irregular since I started just before I hit 15. I worry now because I get frequent sharp pains in my lower abdomin and that didnt happen before.. Any help is very appreciated!
