Low progesterone....help!

Posting again because I got zero response....

Has anyone every experienced high hcg levels, but progesterone levels not doubling? I’m 5 weeks and 5 days pregnant and just had bloodwork done and thats what it showed. I had two miscarriages in 2018 and am freaking out that this is gonna end in another one. My progesterone levels rose but didn’t double, so I’m gonna be going in for an early ultrasound. Unfortunately I’m out of town till Monday evening and they can’t get me in until Wednesday...I’m so nervous and stressed now, just playing the waiting game. :/ anyone else experienced something like this and have a positive outcome?
