Progesterone levels post FET

Hello,

I wonder if anyone can advise on the following please? I had a FET on Monday (24th) and had my progesterone levels checked on Wednesday (26th). They have come back as 48.3nmol/L - is this an adequate range to support implantation?

I understand they will only get higher as I am using 3 Cyclogest (400mg) a day, but am worried they have been too low during the critical period.

Hi @CyanPanda my clinic said progesterone is more important in the later part of the TWW than at first (my progesterone was 37 on transfer day, they put me on prontogest shots and it was 125 a couple of days afterwards)

Different clinics have different levels but I'm sure if they were concerned they'd put you on additional medication but you could always ask for prontogest or lubion ia the other one I've read people use, and ask for a retest - but I'm sure they'd do this anyway if they felt it was necessary
