Hi!
I'm about to gear up for a FET, assuming this month doesn't work on our own (which it never does). I can give you the run down on the timeline and medications, etc when I find out. I know that I will likely skip birth control pills as well. I will be taking Lupron. If so, I"ll begin injecting on day 21 of my cycle, assuming I've ovulated at that point. My doctor said it takes 8-10 weeks for this protocol - but I believe he's including the 3 weeks that I'd be waiting to just start the Lupron injections on day 21. So, that would change it to 5-7 weeks from the beginning of injections. At some point, I would start estrogen - I believe after I get the 2nd period - then a few days prior to the transfer I would start progesterone injections. There are more medications than this, such as I'll take a steroid and an antibiotic, but those are the main hormones.
Each place has their own protocol - some don't use Lupron at all and use an estrogen protocol instead. Some places do a "natural FET" which is different as well -much less medication. My doc wasn't too keen on that.
I've been so curious about the time frame as well. I just want to see a calendar and map out dates, etc. I can let you know mine as soon as I find out ;-)
As far as how many they thaw, I believe it depends on how many you plan to transfer. I plan to transfer two. The way my doctor explained it, he said they would thaw 2 the night before the transfer. If one of them didn't look good, they could thaw another since they can tell relatively quickly if the embryo survived the thaw. My doctor said some people may choose to thaw all of their embryos and then see which are the best, and transfer those back. He doesn't generally recommend that because then the embryos you don't transfer are lost - they don't refreeze them. I have 5 embryos frozen, so it may be a bit different in my case vs your case. There are many variations, and it's up to your and your doctor what you choose to do.
I hope that helped somewhat. I will tell you when I know more about my protocol time line.
Good luck at your consultation!
