I had sex for the first time two days ago, however the condom broke and he came in me. I did take Plan B 7 hours later. I was spotting a few hours after sex, but the blood stopped. When I went to the restroom today, a sufficient amount of blood (bright red) poured out of me, and then stopped. I could tell there was blood when I wiped, but it didn't keep coming out. I am very worried...is the blood from the pill or the sex?
