Help!!!! I’m shook

Okay guys, so my period came yesterday and it started out,

TMI WARNING!!!!!

I knew it came because it was day late and I felt something flow out of my vagina, so when I went to the toilet I was expecting to see blood but instead I say a thick brownish discharge “tmi warning” so much I thought it was feces it looked very much like that except darker, I got confused for a minute and played the watch and see game, while my menses finally seemed to becoming normal now so when I went to the toilet again, consistent brownish blood even light black looking with grey clumpy tissue looking discharge was appearing on the toilet tissue. My mind become racing and I googled and even get glow community to see what others experiences was with this. Most said and commented on other post it was old blood but I had old blood before and after period and it was nothing like this especially now cause throughout the night I had extremely heavy flow the heaviest I had in a long time but this morning this the same it looks like dark red blood and black brown blood with feces ( now I’m seeing brown tissue as well as the grey tissue) and it’s crumbles that sticky like clot blood.

A month ago I had a miscarriage but felt find, I suspected everything didn’t come out because I was around 9 weeks and but I felt find and didn’t even go back for my appointment with dr to see if everything was okay after ( my hubby will probably be mad but after 4 miscarriages I was over it, and was kinda silently not in the right frame of mind ) I don’t think it has anything to do with this though

Currently I only have back pain and terrible public pain and a pain in my shoulder, my legs are a little numb and a little lightheaded but that’s not new

Help I’m freaking out !!
