Hcg level

Valletta
I am losing my mind. I should be 7 weeks. But I think I am only 6. I think I ovulated late. Could see a baby on ultrasound. Hcg only 1498. Waiting to see if it's going up or down. Second blood draw today. I can't think of anything else. The Dr said that's really low.... Everything I see online says that's even low for 6 weeks... I am scared out of my mind....
