I took emergency contraception about three days before I expected my period and I got my period about five days after taking the pill. On the second day of my period in which I was bleeding heavily, I had unprotected sex and my partner ejaculated inside me. It is currently day five of my period and I am still experiencing bleeding, although light. I am aware that the chances of becoming pregnant are slimmer while menstruating but I wanted to ask if Plan B can cause me to ovulate sooner after my period. This would concern me as it would mean I have a possibility of becoming pregnant with early ovulation and the possibility of the semen still being present. Should another dose of Plan B be taken? I am having cramping in my right ovary that I typically feel during ovulation but I'm not sure if these are just period cramps or ovulation cramps.
