HCG levels—previous miscarriages

Jaclyn

I just found out I am pregnant on Sunday

These are my HCG levels:

1/10 139

1/13 348

1/17 1857

1/19 2705

It was doubling but now it didn’t double from Monday to today. Does anyone know if this is normal? I’ve had 2 miscarriages and no living children.

Thanks!
