Last night DH and I were getting busy and it was just a quickie nothing rough in anyway. I also have to add this has NEVER happened to me after sex unless I was about to start my period, if so then it would just start. Well after sex I went to the bathroom to cleanup and notice I was spotting, very light pink though and after that it completely stopped. Still no signs of it this morning. I am 8DPO and 6 days away from my period so its not my period. Could it be implantation bleeding??
