FET Scheduled! How thick was your lining??

Alison • 1st pregnancy twins due Dec’ 19👶🏻👶🏻IVF Fresh transfer 2x, IVF cycle 2 March ‘19 Barbados BFC 🙏🏻🤞🏻, failed IVF 1 and 3 IUI’s in ‘18, immune issues, fur mama to 2 dogs 💕

My lining today was 9.69mm. They want to see it at least at 7 or 8mm before scheduling FET. My FET is set for 9/14. They gave us the option of also doing 9/17 or 9/18. I hate they gave us a choice, I hope we aren’t going too early!! I’m on estrodial now and will add in progesterone tonight. Excited, nervous, and all the emotions🙏🏻🍍😬🤞🏻💓 How thick was your lining for your transfer?
