Miscarriage??

Hey guys, I missed my period for 2 weeks, I kept getting negative tests but had several symptoms which I have had with all 3 kids of mine.

After 2 weeks late, I started badly cramping. It had me crippled over and nearly in tears.

I started spotting then got heavier as the days went on. I was only bleeding for 4days heavy with clots then spotting for day 5.

The bleeding stopped yesterday and today I had to do a urine drug test for family court reasons and while I’ve had no bleeding, when I peed in the cup my pee was blood coloured and had a white flesh looking blob in it, I removed it before handing my test in. When I wiped afterwards there was still no blood on toilet paper.

As I said the bleeding stopped as have most the symptoms, but I am still having bad pains and cramps.

Could this have been a miscarriage? I’m stressing bad.
