Hi! June 18th me and my boyfriend had sex and the condom broke, though he did not finish and we stopped once we found out. Still, I got Plan B about an hour later. I got my period 3 weeks later on July 4th, but its just brown and pink spotting. Hardly enough to fill a tampon in 1 day. Still bleeding July 5th but nothing has changed. Though no other symptoms but mild cramping the day I got it. I took a pregnancy test today and it came back negative. I was going to take a few more this week and next week. (It is hard for me to tell when to take a test because I have irregular periods.) Could the spotting be a side effect of Plan B? (Even though it was 3 weeks before i started bleeding?)
