Baby Fever 😩

My husband and I recently bought our first home and ever since we moved in I have this uncontrollable feeling to have a baby. My hubby agreed to start trying next April (2017) close to the time when he's finished with school, but it just seems so far away. Literally all I can think about all day and night is getting pregnant and having a baby. A few of my friends are expecting and I feel I would usually be so happy for them but i just get so sad. I read books about preparing my body for a baby and pin baby stuff all day long. How can I curb this crazy desire to conceive?? It's like a hormonal switch or something that is impossible to turn off 🙁.
