Its been exactly 10 days since I had unprotected sex and was getting off ovulation and today this mornin I woke up to go to the bathroom and when I wiped I saw two little brown pen drops on the tissue and nothing else couple hours later I wipe and there is Light brown stains on the tissue and brown clump looked kind of like body tissue in a way but since my period is supposed to come in like two days I figured it was my period starting now instead so I put a pad on for the rest of the day and again nothing at all no brown or anything I don't have cramps either, I had some here and there like two days ago but that was it so could this be implantation bleeding? Has this happened to anyone else and was pregnant?

This is something you need to discuss with your doctor.
