Hi Deni,
There are great things about Fly in/out etc type work too, so try to focus on that. If my DH worked normal hrs in the city, i'd probably only see him for a couple of hours at night anyway. Some DPs only see their kids in the weekend, and never get to do all the weekday things like baby check-ups and drop off/pick up from kinder & school etc.
Hope you get BFP this time, so you don't need to worry about the timing side of things for a while.
Good luck
Jo
