I had unprotected sex on the 14th, and the next day took Plan B as a precautionary measure. He did not finish inside of me, but since my period was a week ago I thought it would be best to not leave anything up to fate. On Friday the 19th, we had sex with a condom, but the condom came loose inside of me. He pulled out and did not finish inside of me, but obviously the condom was not there. Today, the 20th, I started bleeding, like a light period. I want to take Plan B, because I am nervous that I am ovulating, but I already took it once this week and I'm bleeding and don't want to cause further stress on my body. What should I do?
