Hi there - I had a HRT FET like Mrs P. I had Progynova tablets also in the lead up to transfer to thicken my lining. It took quite a while and they had to keep upping the dose as my lining was not responding, but eventually it got there. Just prior to transfer I started taking the progesterone pessaries (2 a day - 1 in morning and one at night).
This HRT FET has resulted in my beautiful 8 month old daughter. As Mrs P mentioned, you have to continue on the Progynova and pessaries until your placenta takes over the nourishment of your baby - I took them up until I was 10 weeks pregnant.
I had to have a medicated FET as I have PCOS and a very irregular cycle. I think the FS decides which way to go depending on how regular your cycle is.
