Sorry for the grim photo but I’m at the end of my period and this came out last night. It fell in the loo and sank straight to the bottom - fished it out for a better look (sorry, but I did warn you this was gross).
The texture is hard although the outside has some ‘give’; not at all the soft, jelly-like consistency of normal period blood clots. It’s definitely blood though.
The edges look quite defined too.
I have a telephone appointment with a GP today, but not sure how helpful that will be!
