1 of the 3 top reasons for divorce, one spouse wants a child, the other doesn't. And better yet, if you have one, and she still didn't want it, 99% chance she will love the baby, she will be hostile towards you. I see it all the time. This, like money should be agreed to in writing before ANYBODY gets married.
I was going to post something along the same lines... that there is much risk with pressuring someone who is unwilling, to make such a move, no matter which of the pair is reluctant. The marriage may certainly not survive such a pressured decision. And the marriage may not survive disagreement over such a fundamental life decision. There is risk either way, the only difference is the number of people affected by the divorce.
My friend who just had her baby never said she wanted to be a mother until she married a man who wanted children. Even pregnant, she never said it. I'd say, "Are you happy about this?" she'd say "Tim is". Time will tell how well this goes.
