Help! I'm too young for baby fever

I'm 20 and have been with my big for 14 1/2 months. I'm still in college and know that I am not financially stable enough for a child. I've been having some missed periods and took tests all BFNs and I realized how disappointed and upset by this that I actually was. I feel like now I have baby fever, I get excited to see the baby aisles at the stores and get very happy when I see children and I can't help but want my own. How do I curb my baby "obsession"?
