5 week Quant #s

Famof4finally!!👨‍👩‍👧‍👦

Hi ladies! I'm 5 weeks with my 2nd. Had my 4th beta done yesterday and my HCG was 3100 but my progesterone was only 9.5. My nurse didn't seem concerned. I go for my prenatal ultrasound and appointment on the 21st. Is my progesterone too low for 5 weeks?

I had to go the assisted femara route this pregnancy so I'm a little worried.

Thanks
