Babies

I need help. I'm 17 and my boyfriend is 14. We both wanted a kid and was planning on it when I'm closer to 18 to try and now he believes he hears a heartbeat and we have DHS, I believe it was called, called on us. Anything you can give us as help? We are planning on getting married when he's 16 and are already saving for the future and looking for houses. Thanks!
