One thing I've learnt from my journey is that you don't have a whole lot of control, and I'm like you, I like to have everything thought-out and planned... it's been a tough 'life lesson' to relinquish control!
You might also want to ask about freezing eggs rather than embryo's if you're concerned about your 'future' husband. Although, I have a feeling that this process is not covered by medicare unless you are going through treatments like chemo. I believe IVF-A and Genea both offer this as an option though. Sister in law went through Genea in Sydney for PGD and was sucessful, they are highly recommended (if I lived in Sydney they would be my choice).
Best of luck with everything, this forum is full of support and advice if you need it!
