Back story:

Feb 4th my hcg was 20 feb 18th my hcg was 770 but I start spotting very light pink feb 20th hcg 1198 spotting started getting bridge red and cramps started coming in on/off. Sunday the spotting was still red today is Monday my dr canceled my appointment I originally had when they thought I was 7 weeks pregnant. They ordered another hcg this morning told me we have to wait for that to come back. I’m still spotting and my cramps hurt and they have been consistent today. Dr told me they don’t know why I’m bleeding nor will they see me because they can’t do anything about it. But I mean can’t they look via scans to see where the bleeding is coming from? Ugh I’m scared
