I had unprotected sex, then the next day bf told me he thinks he came inside me so I took plan b. Immediately after we had sex again and he came inside me thinking it was okay because plan b was in my system. (I'm aware that that is false, and yes I know get on birth control and dont have have unprotected sex) 6 days later I had a brown discharge and began to have a light period all day yesterday. Just wondering if anyone's gotten pregnant from having sex immediately after plan b?
