⚠️TMI⚠️ Could this be a miscarriage?

Yesterday I was in the shower, shaving everywhere. Saw a little black thing hanging from my vagina and pulled it out and the next 5 pictures is of what came out. Horrified to say the least I have no clue what it could be and I’ve never had anything like this before. I wouldn’t be posting this if this had only happened the once… my period is 7 days late but usually is irregular and lasts longer than a week at times.

The next few images are what I pulled out of my vagina 2 hours ago when I was getting changed…

Can someone please shed some light on what this could be never ever seen anything like this before!
