Hi CHJH, and welcome back. I have already undergone one FET cycle and started lupron just yesterday on my second FET attempt. Theses cycles do require medication and monitoring, however, a fresh cycle requires a whole lot more of both.
As for meds, in my case, BCP (5 weeks) is required to regulate my cycle and quiet my ovaries. A few days before my last BCP I start lupron injections each morning. About a week later I start taking estradiol each day. (I take this in form of a pill, as much as 2 pills 3X/day, but I know some people have done the patch or the suppository.) A couple of days before the transfer I start the progesterone injections which I continue until beta (ouch! these really hurt
). I visit the office for no more than 2-3 u/s's during this entire time period to confirm all is quiet and my lining looks good.
The first FET, we thawed 3 embryos and since all survived we transferred all three. None took. They were 4 cell, 5 cell, and 6 cell (grades C, B, and B, respectively). Since I still have 12 frosties remaining, this time I requested they thaw 6 and we see if any of them can make it to blast stage (I think that's at least 36 cells, right?)... if they don't, then we'll thaw the remaining 6 (which are at the morula stage) and transfer the 3 best at that time. So blast is def what we want!
Hope this helped and good luck to you!!!!
