Possible Miscarriage...? TMI Pics *trigger warning!!*

Mearia

Ladies, help!! My period was 9 days late, and from 6dpo I started experiencing mild nausea, fatigue, and breast tenderness. I never had a positive pregnancy test, and when I started spotting I just figured I'd psyched myself out and made my period late. Well I started, but I'm still bleeding 11 days later. Yesterday I started passing big clots (not totally out of the ordinary for me, normally I have 2 days of intermittent quarter sized clots). This evening I thought I had finished though as it had been several hours with no bleeding, so I decided to take a bath. I sat down in the tub, felt a weird bubbling in my lower abdomen, and within 2 minutes the water in the tub was completely red. Needless to say, I drained it and turned on the shower. While cleaning myself in the shower, I pulled the tissue in the picture below from my vaginal opening. The long thin part was hard and stretchy like an elastic, and the darker clot had a hard center.

Am I being too paranoid or does this look like an early miscarriage?
