Bleeding post ovulation

Amanda • Wife + Mom to sweet baby girl born 9/3/18 🌺

Hi, I'm hoping someone can help me out or give me some insight. I'm currently TTC, and just got finished ovulating. (All the green days on the Glow ended yesterday. Sorry I'm not down with all the TTC lingo yet.) My husband and I had sex once every day during that ovulation period. This evening when I got home I noticed I had a significant amount of blood w/ a few clots when I wiped. It wasn't worrisome, as I'm a person who regular has light bleeding during peak ovulation. However, I'm feeling confused since I'm supposedly no longer ovulating. I don't think it was implantation bleeding since it was bright red and contained several clots. But what other reasons could be causing the bleeding?
