What Causes Dark Vaginal Clots Along With Bloating Post Intake Of Morning After Pill?

Hi, Ten days ago, right after the end of my period l, I had unprotected sex with my bf and I m not in the pill due to polycistic ovaries. I should mention that he didn t rekease while penetration. The next day we got the morning after pill and 5 days later I started having dark clots, bloating, constipation, and cramps. I do not believe that I m pregnant as we only started having sex 1 week prior and I hadn t had sex for a year before that. Are these related to the pill, is that a plausible explanation.
