Honey don't worry yourself. You should go to a planned parenthood now that you are being a responsible adult.
The brown discharge is normal if you are around your period. It could also be breakthrough bleeding.
3x a week isn't enough to be too much. I like it that many times, if not more per day:)
Good luck.
why on earth would you scare a 16 yr old little girl like that? did it ever occur to you that it might just be breakthrough bleeding? if its brown then its just old blood. when youre on BC you can have breakthrough bleeding especially if you miss some pills.
Oh, honey, you have an STD. Kick him to the curb, get to your doctor (pray it's one that is curable) and use a condom EVERY TIME - NO EXCEPTIONS!
u should see with a doctor it could be a std
