Spotting during sex ?

Danielle • TTC #1 with PCOS 👼🙏✨

Okay, so while me and the hubby were having sex I started to bleed. I only knew cause I had to pee in the middle of it and when I wiped I saw pink. So i assumed that I was going to begin my period. There were times where I did start my period during intercourse but...when I went to change my tampon there was no blood? Just discharge. Anyone have a good explanation for that? Or maybe I’ll just get my period soon? I hope not since we are trying...
