Baby #3 - stressed on timing

We have two boys, 6yr. next month and newly 3yr.

We are trying for a third BUT I feel stressed and selfish.

We are moving to another state the 1st week in June, hubby starts his new job June 15th. I'd like to get pregnant asap but obviously I want to get moved before we have a baby. And on top of it our second sons birthday is July 17th. And I'd like for him to keep his special day for his own... but this is where I get selfish, I want to conceive asap, sigh.

If you could get pregnant as planned what would be your ideal due date? Help.
