I took plan b 3 or 4 days after my period in late April 26 ... 8 days later my period came again in the beginning of May around May 4 or 5. Now it is May 23 and I am bleeding like I have a period again. Whats going on? Please Help. I'm worried. Also yesterday and the day before my boyfriend and I was having alot of rough sex. And right after we had sex the last time that's when I noticed its a lot of blood. Then now I'm cramping like a period. We did use condoms
