We did not have unprotected sex but she rubbed up against me and I had a little bit of semen. She claims she only felt my pants and I also did not feel anything but 30-40 minutes after she took the plan b one step. This happened Wednesday, it is now Saturday. She says she feels like she is getting her period because she always feels this way when she's about to get it. However I am freaking out, she hasn't had any side effects from the pill. How likely is it that she is pregnant? Even if she took the pill without needing it, will her period cycle still be messed up? This really was all bad luck we were not even planning on having sex that day.
