for the past few weeks, when i have sex with my boyfriend i tend to bleed afterwards. then the next day the bleeding will stop. im on the birth control pill junel. ive been on if for almost a year now but ive nvr had this problem. the only thing i can think of is it may be coming from a diet pill which also supposedly cleans your system called hot detox. because i havent had a period since ive been on the junel pill. any ideas what may be going on with me??
