My previous FET cycle which was modified natural failed. It did not implant. my lining was only 7.2 mm so could have failed due to that. I was taking progesterone suppositories twice daily and on my day of transfer my progesterone was 24.7
My RE wants to add PIO in this FET cycle besides progesterone suppositories three times daily instead of twice.
If my progesterone gets really high on the day of FET couldn’t that negatively impact the implantation rate?
I read that high progesterone can also make the lining non receptive. My level was 24.7 with 2 suppositories per day.
