How long are you going to wait after the wedding to try to get pregnant?

We are going to wait a long time though we have been together for over 4 years now. I am 26 and I know (because I hear it EVERY FAY from my female relatives!) that I am not a young buck and should get cracking, but Iam still finishing my undergrad because I worked for a few years then went back to school part-time. I will be done in December God-willing and then I have to get my masters (requirement for teachers) and THEN I want to work my way up to an AP position so that will take another few years... so we are looking at mm maybe 35 for me and 41 for him when we have kids? That also becomes an issue because FH doesnt want to be 40 when we have kids and neither of us wants to have them tomorrow, because I want to be able to stay home and take care of them soooo...

-shrugs- who knows. Baby fairy might not come visit us ever.
