Hi, I had unprotected sex with my boyfriend on the 31st of January, but he didn't ejaculate inside me. I wasn't ovulating (my period is due on the 5th) and I took Postinor 2 on the 1st of Feb just in case. I'm now experiencing light neausea but I'm aware that it might also be the side effects from the pill. What are the chances of me getting pregnant? How long should I wait for my period, or will it be delayed due to the pill? I'm stressing out.
