HCG rising but not doubling

Aryn

1/16 - HCG 102

1/18 - HCG 196.4 … 92% increase

1/20 HCG 245 … 26% increase

I have a history of miscarriages but never had slow rising like this. Any one else ever go through this? Waiting on doctor to call me in regards to todays test results. I’m scared if ectopic

Update: doctor wants me to come back in a week for another blood draw. Im to watch for bleeding and continue to take my progesterone
