Baby fever

Hey everyone.... It seems like everyone around me is pregnant or having babies. My hubs and I have been together for 6 years and I'm more than ready to start having kids. He is concerned bc we aren't financially stable right now which I agree with but I'm having a really hard time being happy for our friends who are expecting. It seems like every week it's someone new getting pregnant or popping out a kid.... Does anyone have advise for me to get past my own dreams of being a mom and be happy for our friends I feel like a horrible person for being upset that they get to experience children and I'm stuck waiting. Thanks everyone.
