Miscarriage and bleeding *TMI*

So I had a missed miscarriage that began naturally passing on monday when I was meant to be 12 weeks (baby had died at 9 weeks), on monday I had excruciating cramps and passed baby with lots of clots etc

Then tuesday and Wednesday the bleeding hasnt been that bad, heavier than usual for a period for me but manageable, however today started the same and then this afternoon I've had really bad cramps again and really heavy bleeding and clots being passed

Just wondered if this was normal?
