I have been on birth control for 5 years or so. I take it 3 months straight and then a week of the sugar pills for my period and then another 3 months and so on. I got my period on the 19th of February and then it was gone on the 24th and my fiance and I decided we want to try to conceive so i didn't start back on my pills and we had unprotected sex the 24th and right after i got my period back and the next morning it was gone. then the 26th i had a little brown discharge. then we had sex again on the 27th and everything was fine but now today (the 1st) i had more brown discharge?? I'm not sure what is going on...my period is gone so why am i still getting this brown discharge?? i don't know if its really discharge from my period, or withdrawal from the birth control, or from the sex or if I'm pregnant???
