4 weeks 3 days bleeding

Aubyrn • Freelance Artist//Mom to 2 boys
I have been cramping and bleeding since Monday, it is still happening and it is now Wednesday. I had my first ob apt yesterday morning and they couldn't find anything on the ultrasound (which is normal right?) and took blood. I go back Thursday to have more blood drawn and we will know if my HCG is doubling or if something is wrong or I miscarried. I'm just really trying not to be stressed about this , but I can't help it. Anyone have good or bad stories with this happening to them?
