I am 34 and had sex for the first time 2 days ago and it was unprotected. It was a day before my period was meant to start. I noticed a bid of bleeding after and have been bleeding a little since but have had no heavy flows as I usually would have during my normal period. I made sure that I took a morning after pill a few hours after. My questions are is it normal that my period would be so different. How long does it take before the pain goes away?
