I’m currently on cycle day 24 after a 3rd round of letrozole 2.5g.
I think I ovulated around cycle day 8/9 as I got a positive pregnancy test on cycle day 21. I’ve tested daily since and the lines have darkened and seem to be progressing.
as part of the fertility referral and letrozole treatment I have progesterone bloods on cycle day 21. They have come back as 15.9 nmol/l which seems significantly low and suggests not high enough to sustain a pregnancy.
the clinic have just told me to call back with my pregnancy test result when I’m technically 4 weeks and don’t seem helpful on giving me progesterone pessaries.
has anyone got any advice or positive stories in a similar situation? Can progesterone rise quickly after a low result? TIA
