hi this is my first time useing this and I'm not sure how to explain this. Well , about 8 days ago I was ending my period and had unprotected sex while still on my period , he cummed in me. I am on birth control so I thought everything will be ok. although , today I felt all of a sudden something wet and when I went to go check I had light pinkish blood. after that I had nomore bleeding it just stopped completely, and I have about 12 more days till my next period . I have no idea what this is or could be ? any answers ?
