We're hoping to start our first round of FET soon, but I have a holiday planned am and not sure if I'm being unrealistic with wanting to start this cycle (got my period today). We had a successful fresh IVF about 5 years ago, so I have forgotten some of the basics 
So I need to start downregging on CD 21 ( buserilin injections I expect) how long approx does downregging take? Will I need scans through this period, or only once I have bled? How long is that likely to take?
I'll then be taking Progynova to thicken the lining. How long approx does this take? Will I need scans, and if so after how many days of taking the tablets?
Sorry for so many questions - I hope it makes sense
TIA
