Pregnancy levels

So I got my levels back today after my 3rd bloodwork. hCG is up to 120.2 from 44.2, 2 days ago. My progesterone levels have been going down since my first bloodwork. My 2nd bloodwork it was 11.2 and my most recent bloodwork was 10.53.

Has anyone had low progesterone and had a successful pregnancy? What are the chances of ectopic or miscarriage? Were you able to take progesterone supplements to help keep the pregnancy viable?

I’m going nuts, and no one knows how far along I am. From my LMP, I should be 6w5d, but when I went in for my first bloodwork, they said somewhere between 2-3 weeks. First ultrasound is scheduled for next Tuesday to check on viability.
