I posted this in conception but I wondered if anyone on here had any thoughts....
I had some 21 day bloods done last week to check progesterone levels after 2 mcs (I've had some slight spotting before af, but not a lot). I get those results on thursday when I see the doc. However, if I got a bfp before then, would that pregnancy have a chance if it turned out I did have low progesterone levels? How early do you have to start taking progesterone supplements to prevent a miscarriage?
