Caesardust - my last and current cycles I have done hrt fet's. I was put on this type of cycle as my first fet was too unpredictable and I didnt react as expected to the stimulating drugs for ovulation think I had become resistant. Have to say the hrt protocol is so much easier to control and reliable also less scans and bt needed. I cant say how well they work in comparison yet though as haven't had a bfp. The only down side is you produce no natural progesterone so have to stay on both progesterone support and estrogen throughout your first trimester if you get your bfp. Hope it works for you hun.
