graphic picture! what is happening?!?

My husband and I are TTC. My period came 5 days late this month and before that, I had the cramps and the world's worst nausea for almost a week and a half. My nipples were also incredibly sensitive. These are not typical symptoms for me. This morning, I found this which had leaked through my tampon. I've never seen anything like it. Any thoughts? Did I miscarry? Thanks so much in advance.
