Bleeding with ovulation (sorry for the TMI)

Emily
I'm day 15 of my cycle and currently on my last day of ovulation. A couple days ago was my peak day. Anyway yesterday I had some cramping and noticed some light blood when I went to the bathroom. I didn't think anything of it because I know that's sometimes common with ovulation. However, this morning when I went to the bathroom there was a decent size chunk of blood in the toilet. I'm not sure if it was a clot or what. Now when I wipe there's still some blood mixed with a clear mucus discharge. I feel like I'm having a second period. Has anyone else had this issue?
