About 3 weeks ago (March 17), I had sex with my boyfriend WITH A CONDOM. Then a week after that (March 24), we had sex with a condom again, but the condom broke. We noticed INMEDIATELY right when it broke and stopped. It ripped at the tip of his penis. About 11-12 days after this experience, which is my period due date (April 4) I have had a heavy period that lasted only a few hours. Less than a day. Then a little came back a few hours later. Is this implantation or menstrual spotting? Am I pregnant or not? Can I still be pregnant if I get my period?
