I had sex with my boyfriend August 5 and the condom broke. I took next choice emergency contraceptive the next day and on the 14 thru the 17 I though I had my period. Two weeks later I had some spotting that lasted for about a day and a half.two weeks later (today) September 11, my period was supposed to start but all tht seems to be coming out is brownish and really is not a flow at all. Is it possible that the medication messed up everything? I've never had spotting until this time and usually my periods last about 5/6 days. I'm really nervous. I don't really know what to do. Any advice?
