Hugs, Phy, sorry for the downer.
I didn't mean to come across as saying "don't do it"; my intent was more to be sure you were consider enough factors going in. And this is because there were emotional and physical aspects of pregnancy that I, not having been exposed to others' pregnancies, found unexpected. You may have already factored a lot of these in.
NYC's right though that mental focus the first few years is tough, I'd say up until around age 3.
That said, when you want to be pregnant and you're not, that of itself can be a huge distraction and emotional disruption (been there too). So I understand that it would be hard to forgo right now. Tough decisions.
