extremely tmi Early miscarriage?

I was 7 days late with two clear faint lines. "Af" came two days ago and has been heavy- kinda light- and kind heavy back and fourth. Haven't been SUPER crampy but had lots of stringy "clots" like tissue. A bit ago I had extreme pain and ran to the bathroom- felt like super duper heavy pressure in my vagina ( still having it now kind of ) then huge clots came out one by one! 😥😓😵 is this an early miscarrge? I suspect that/ chemical pregnancy! I'm so scared and calmly freaking out inside but idk what to think!
