Hello. My last period came 3 days late and was on 23rd to 27th November so it ended one week ago today. This morning after using the bathroom I wiped and there was bright red blood on the tissue and a few drops in the toilet. There is no blood coming out only when I wipe. I had sex last night with protection could this be why I'm bleeding? I have never bled in between periods and I've never been late on my period except for the 2 times I was pregnant. Thank you
