I had sex with my partner and the condom broke on Sept 19. I took Plan B within 12 hours, on Sept 20. According to my period tracking app, my ovulation would begin on Sept 25. This means I took Plan B four days before ovulation. On Sept 25, I started spotting. The next day, I started bleeding as if I’d had a normal period. Today (Sept 27) is day 2 of heavier/normal period-type bleeding. Is there a chance I could be pregnant, given that I took Plan B 4 days before ovulation? I’m worried the spitting/bleeding on the day of my ovulation means it could be implantation bleeding? Please help, this has never happened to me before and I’m really scared.
