I'm with him too @Caesardust. My previous nurse discussed my history with him (I wrote down my lining measurements for each cycle and emailed it to her so she could see at a quick glance that me reaching 6-6.5mm was my normal) and he agreed to a transfer at anything above 6mm. I've re-emailed my new nurse seeking a written assurance that he will indeed transfer at 6mm. I've also reiterated that I won't take Synarel for longer than 14 days. I'm awaiting their reply. I've got a bit pushy after my last cancelled cycle! I'd also recommend emailing your nurse and CCing Dr LR seeking the same reassurance. Then there can be no confusion.
So your first lining scan is in about 10 days here in Melb? Then how many days after do you fly out?
PS: don't forget that you can claim your $180 lining scan with Medicare personally. If you've reached your SNT then they'll only cost you about $45, so it's not too much of a financial hardship if you'd like to have an earlier scan at day 14 to see how much it grows in one week.
