HELP!!!!!!!!! TMI TMI TMI I am TTC but got my period


I about 3 days ago got my period. I was 11 days late and thought for sure that I was pregnant. But maybe I’ll have better luck next month. My SO tries his best to keep my mind away from being sad but it’s hard.

Anyway....the reason I’m posting is because I am confused about my period blood. It has what looks like fertile mucus in it. And I’m not sure how this is possible. Does anyone know what’s up with what is going on? Anything?

I would have posted picture but too embarrassed and believe it’s too much.
