okay so i have sex a lot with my boyfriend and im on the pill the other morning i bled very very lighty for 5 minutes and im not on period its not due for 2 weeks and then i was in my room doing splits(im on a dance team) and after i did them i realized there was some dark brown stuff coming out and it wasnt coming out before i did my splits. me and him had some pretty rough sex but im very worried about what made this happen. i checked my ovulation chart and it said that im ovulating now so im not sure if thats what made this happen
