Think I’m miscarrying

Victoria

Confirmed pregnancy at 9dpo with test.

Typical pregnancy symptoms

This morning work up one week after period was due with heavy blood

Rushed to the emergency room sonogram doesn’t see anything

Blood test comes back positive

I’m so so scared I have to go back in two days to get blood work again to see if the hcg goes up or down

Has anyone had very heavy bleeding at 5 weeks pregnant with cramping and not miscarried ??
