I had sex on April 13th with protection. He ejaculated inside the condom, I saw. Took a plan B after that 10 hrs but to find out it doesnt work on women who are overweight. I got my period after 2 weeks from that night or so. It was pretty heavy...lasted about 4 days or so. But now it's May I'm waiting for my period again (just in case) around the end of the months...my periods sometimes changes due to my heavy weight. So its confuses me sometimes
