@Corbes My understanding is that they like to see your lining ideally between 8-12mm's for transfer, but anything 6mm> is the bare minimum so you should be right. How many pessaries are you taking??
@Caesardust Sorry, I mixed up the Sandrena Gel (which is estrogen and used to help thicken up your lining I think??) with Androderm Gel (which is Testosterone and used as an alternative to DHEA for egg quality).
I'm not sure on when you should start taking it??? If it's to help thicken up your lining, then it's probably ok to start it tomorrow. They use Progynova tablets to do the same thing With the Crinone, I used it 2x a day from the day after EPU. On transfer day, I didn't take it in the morning, just that night, then 2xday after. That was in Cycles1,2&3.
