Need advice of if I should have a baby now or later!

Well, me and my bf haven’t been together for too long but we finally have our own place. I’ve been wanting a baby since I was really young but it’s never happened for me with any of my exes, I’ve had two miscarries with only one of my exes and I long to be able to hold my very own child. I work at a daycare and it makes me very depressed not to have none of my own babies with me at work. I am very much in love with my bf and we want to start our future together. I’m ready for a baby but I don’t think he is. We’ve had a pregnancy scare before but it didn’t scare me it scared him more. How should I talk to him about it? Should I just wait on trying for one?
