I had unprotected sex twice in 2 weeks with my bf in the middle of Feb. I got my period on the 21st of this month and it so called ended friday and now I have cramps and i noticed I spotted. What does this mean? I am worried because my doc said I have PCOS ( polycystic ovarian syndrome? Which causes infertility, so I couldn't be pregnant right? Even though I am on the pill as well?
