What do you do when...

What do you do when your parents/family doesn't agree on you trying for a baby? 
I'm 22, married with a man who has three kids already so it's not like I can "go out there" and "see the world". Not that I want to. I'm really content with being a mother. 
We're trying for a baby together. This is our second month. 
My family doesn't think we should have a child just why. They say that we should be financially stable. And that we should wait about a year. 
We're pretty fancially stable, we're not rich but we're not completely poor anymore. 
I just worried that once I get a positive they won't be excited for me.. Someone please share your expire nice and hope stories! Thanks!!
