Possible miscarriage? Graphic photos, im sorry.

Graphic!!
I have had 2 miscarriages this year.
I havent had my period since my last miscarriage, my doctor told me this is normal. I've also been on the mini pill and taking it religiously.
On Sunday I started to bleed, presumably my period so I didn't think much of it.
But last night I woke up with horrendous cramping, i could barely breathe and could not move. Then when I went to the toilet today I was met with this, dark red lumpy mess followed with pink discharge.
I then had no bleeding for 3 hours followed by this odd stringy thing that was actually stuck inside me...
If I was pregnant I didn't know.
