What would you recommend parents-to-be do in their last year before TTC via fertility treatment?

My husband and I will only be able to conceive via IVF for medical reasons, so we've been starting to save for the upcoming out of pocket costs. This will take us a year or two to do, so we're trying to soak up our last couple of years before parenthood.

For those currently in the process of fertility treatment or who have already gotten pregnant, what are things you wish you did with your partner before you started? For those who intend to be/are pregnant, are there things you wish you'd done for yourself before conceiving?
