This made me think of something that my old boss said to me after I got married ( we were close)
She said "Are you going to have kids soon? There will ALWAYS be a reason "not" to do it or something that makes you think you shouldn't or should wait. There will NEVER be a "perfect" time. If you want to have kids, have kids!"
That being said, its REALLY good you ARE thinking of the future and what would change....
Go with your gut. When we changed countries from Peru to Guatemala, we decided to wait about a year or so. And then all the sudden, like a day or 2 after deciding to wait, we just said "no, lets do it now". Just out of the blue, and it was just... right. And it felt right to.
