TMI PHOTO!❗️Blood?

Zas

So today marks 2 days after the end of my fertile days. Today I was feeling super bloated suddenly. And was spotting very little. Suddenly i started to bleed a lot and in the toilet I see this. I’m not peeing blood.. it seems as if it’s thin blood from my vagina with some clot thing at the bottom. What could it be? I have 11 days till my next period and my last period was about 20 days ago
