Low Progesterone ?

Janecia

At 6w5d I got my blood work done... I checked my labs on the app, says my Progesterone levels are at 8.33 😭😭 when I researched this is a low number... I didn’t get a call from my doctor that my levels were low... HCG levels were at 20,000... I have an ultrasound tomorrow, my first one. I’m super stressed about this...does anyone truly know what’s considered low levels?

I’m currently 8 weeks 2 days.. no spotting. Just sore breasts & have been nauseous with headaches.
