I used the plan b one step twice last year. I did a little research on it before I took it and it said that it isn't an abortion pill. I was scared because me and my bf had an accident with a condom in top of that I ran out of my bc pills. Well anyway I'm so paranoid because I've never been pregnant and I feel like the plan b may cause some infertility. I know, crazy lol but I say that because me and my bf had unprotected sex a few times but not enough to say that I'm infertile. I guess I think I am because I nevrr got pregnant on the unprotected days.
