My boyfriend and I had sex the day my period was supposed to start. He pulled out with the condom and didn't realize that the condom broke. He doesn't know if he came inside me or not because we always pull out with the condom on. I am on birth control as well. I washed off and took plan b less than 30 minutes after we had sex. Within an hour I saw blood and thought it was my period. As the day went on it got lighter and brownish. I spotted (brownish discharge) for 5 days including that day i thought i started. Am I good?
