HCG level help!!!

Sara

I am 6w5d today( got this date from my app) and for the past 6 days I had to get my hcg levels taken. Last Tuesday My doc thought I was 6/7 weeks (I ovulated CD 20) I went for an early ultra sound and saw a gs sack and a yolk sack but no fetal pole. I have been stressing all week I don’t have a viable pregnancy.

My levels are not doubling but they seem high

5w4d-12000

6w- 20000

6w2d- 26880

Has anyone not had double numbers and had a healthy pregnancy??
