BW,
I am the queen of FETs and different types of FET. Originally I waited and waited till I got a positive O..this could be either with LH tests then confirmation with BT.This often stretched my cycles out of whack completley to 45 day cycles and I hated having to wait and feeling like a failure as Ovulation wasnt something my body didnt want to comply with..then I went to progonova tablets (which I think is estrogen) and waited for O with the help of ultrasounds to check the lining if it was thick enough...Finally I went on to stim drugs...Puregon then a trigger and then a transfer 3 days later, the same as a 3 day Stim cycle. Then all supported with progesterone pessaries till day 14 DPO. I think on the MIVF website it was something about sucess rates on FET's but keep in mind what is frozen isnt necessary the best quality. As for me ...One preg from Fresh, 2 from FET's.
