Slow rising HCG

Keia

Hey ladies, I have pregnancy anxiety SO bad 😩 despite every single ultrasound I’ve had being good with strong heart beat and measuring perfectly I can’t help but wonder why my HCG is not doubling. Granted I haven’t done them 48 hours apart but I’d just think the numbers would be higher. Sept 14-2259

Sept 20-9783

Oct 16- 67227

My last ultrasound was Oct 16th I was measuring right at 10 weeks heartbeat at 170 and baby just moving all around. Should I be concerned?
