Opinions?

Okay, me and my husband have a daughter together. She'll be a year old on Feb. 1st. We have both agreed we would like to have a boy one day. I'd like to start trying now, but he wants to wait. #1 because we are not in our house right now and #2 because he says it will "happen when it happens" Should I just suck it up and wait? Or should I try and keep talking to him about it and maybe change his mind?

*Note*

I want to try now because my daughter was a rainbow baby and I was told I'd never have a child. I have also heard you're more fertile after having a kid. I don't want to risk waiting only to be told I'm infertile again.
