I had sex 7 days after the first day of my last period and the condom broke. I took Plan B the next day. And 6 days after I took the pill, I had my period. It didn't come with typical period symptoms like tender breasts and cramps. I know the hormone in Plan B can mess with hormone levels. It's not very heavy but I'm wondering if, after all of this, I could still be pregnant. Can I say I'm in the clear now that I had my period, however irregular? Please someone help me.
