I'm currently pregnant I don't how many weeks according to my text I'M 4-5 weeks pregnant my hcg level went from 787 to 2200 then 2 days later it from to 2400 not so much of a jump like I wanted my ultrasound showed no baby or sac
My progesterone level 1.92 which is so low but there no baby in my tube either
So I this point ca this be a normal pregnancy ? It is too early to see anything ? Or should I take progesterone shoot to try to save my baby need advice please

Since hcg levels will vary widely, they can only give you an idea of about where you might be in early pregnancy. Your progesterone level could be perfectly fine. Your doctor will let you know if progesterone would be beneficial or not. You can always call them to discuss it. So much can change in the early weeks; a matter of just a few days can make a difference in what is seen on an ultrasound.

Your doctor will likely repeat a scan within a couple of weeks. Hopefully at that time you will have some more peace of mind.
