I took the fourth pill of my pack 7 hours late a couple of weeks ago but then quickly made up for it (took the late one right when I woke up then took that day's pill that night at my regular time) then continued to take the pills after it very religiously and on time. The day I took it late I had sex with my boyfriend and he did not even come close to ejaculating inside of me if it makes any difference. I am due to have my period in one week (6 more active pills) and I am experiencing a very light brown discharge and slight cramping. I am extremely scared that I might be pregnant.
