Convincing partner?

So I have a question for those of you trying to conceive under 20. What is your guys situation that makes it ok to start trying? Me and my boyfriend have been together for 4 years we are 19 leaving on our own we both have stable jobs and I so badly want to have a baby. He says we need to wait and doesn’t want one right now, I’m obviously not going to try and have a baby until he is ready as well. I would say the only thing that would be hard is that I’m still in college, and i know that would be much more challenging with a baby. I just so badly want to be a mother and its honestly so hard waiting. What have you guys done that your partner also wants to have a baby so young?
