I want to have a baby!

Okay so I'm 17 and I don't need you to tell me why I shouldn't. Both my mom and his parents would love for us to have a baby, and are supportive of the idea. Back in June-August I had a molar pregnancy, we were ttc to conceive when this happened, and it was heartbreaking. And we couldn't start trying for six months because they have to monitor after a molar pregnancy to make sure it doesn't come back as cancer. But now it has been six months and so we can start trying, but he's scared still. I'm not sure why, I know he still wants a baby, just as bad as I do, because he says he does and just the way he acts with kids, I feel like I can see it in his eyes. So anyways I am going crazy because I just want a baby so bad and having the molar pregancy just made me realize how much I want a baby even more. Sorry this is so long, but I'm losing my mind.
