Gray discharge or tissue?

At 8 weeks pregnant After having intercourse w my husband, later that day I can't tell if I had gray discharge or tissue passing because I let my husband ejaculate inside me. (TMI sorry) It was really small, right before hand I had some white discharge mixed w some blood which is normal my OB said for it to bleed because I have an extremely sensitive cervix. I had just seen the baby the previous week, heartbeat and all. She also did a pap, which made me pass tissue which my OB said would happen.
