bleeding, clotting at 5 weeks and 5 days

Sarah
I had like 4 positive tests last week and had hcg taken yesterday and today it came back at 3,000 but this morning around 10am I had a gush of bleeding and then later on this afternoon lost a clot the size of my palm maybe a little smaller then a few smaller ones and another larger one later on. I'm not having like any cramping which has me puzzled! This would be our second miscarriage in a little over a year :( anyone else have this happen? Also isn't 3,000 high for hcg! I'm going tomorrow for my 48 hrs hcg level. The bleeding stopped around 4pm and I've just slightly spotted since
