Okay, I'm a 21 yo woman. I am a type 1 diabetic since 2005, I was diagnosed with PCOS in 2009. Last year I was put on Provera because I don't have periods. I went on BC about a month ago, because we were having problems with condoms coming off. Right before I started BC I just got off Antibiotics for an infection. Now I'm having an extremely heavy period with tons of clots, bigger than a quarter. If I don't change my tampon at least every hour, I bleed through my clothes.
