@pingc383 if you are not transferring within 3 months then probably do the scratch at a later date. Make sure you get report and photos of hysterscopy released to wazza. I would personally prefer wazza to do hysterscopy as he is the one doing the transfer so I want him to know my uterus well!!!!but having said that, dr M is a very experienced ob, I wish he is based in Melbourne!
Sounds like you have a good plan in place!
