Jealous

Is it just me or does it feel like everyone is getting pregnant!? I'm engaged and my fiancé wants to wait until we are married (in 2017) to TTC but I've got baby fever now! Literally all of my friends are announcing their pregnancies and posting beautiful pictures of their bumps and I'm so incredibly jealous. Is that wrong of me? I'm upset and I can't even do anything about it until 2017. This is heartbreaking! The reason we are waiting to get married until 2017 is because we both graduate college that year and we want to be done with college so we can't move the date up either. I'm getting incredibly impatient. Anyway, I feel like a bad person for not being totally stoked about all my friends getting to start their family now but I'm having to wait. What do I do?!
