Wedding and a baby?!

My fiancé and I are getting married in August. I've been told I would have a hard time getting pregnant since I was a teenager. We both want to start a family when God will allow us and mostly whenever we can get pregnant. We don't use any contraception and with the stress of nursing school we sometimes don't have sex for a week or two. I'm trying to be patient because I know good thing happens to those who wait but I really don't want to wait anymore and sometimes he says the same thing. To be honest, I'm not sure what I'm asking or where I'm going with this.. But I know that I don't want to wait forever to have a baby since its been two years since we started go try. I feel silly for asking but what do you think we could do to help ourselves mentally / emotionally with this. Thank you 😊
