I had sex with my boyfriend on a monday and on a friday of the same week. Saturday was my first sugar pill of the pack and im on the 3rd one now and my period still hasnt come. I have been on the pill for around 3 months going on four. When i first started the pill i had alot of trouble with my period it never seemed to stop.I thougt it was sorted out now but i dont know. Is it possible im pregnant or is it something else?? We used a condom and it didnt split or anything, and he didnt cum either of the times we had sex. What happening??
