Dear blondie,
these are the normal progesterone levels for pregnancy:
1st trimester 11.2 - 90.0 ng/ml
2nd trimester 25.6 - 89.4 ng/ml
3rd trimester 48.4 - 422.5 ng/ml
is that what you meant ? Yeah your doctor is right, they are low but i'm sure doc will keep a close eye on you and it should be fine. Are you recieving progesterone replacement therapy ? I'm not sure if it will affect your pregnancy or not, but from what I know about low progesterone levels is that it can sometimes send you into early menopause. I hope that helps.
Regards,
