Right I had sex early morning 21st of Feb, took the emergency pill but like 64 hours later. My period then arrived 7th of march but it was a lot lighter than usual and I experienced cramping I have never felt before. I was supposed to start my period again on Sunday but it is 2 days late encounting. I took 2 pregnancy tests about 2/3 weeks ago that came back negative. I had sex around ovulation day I think.. Ah what is going on?! :/
