Waiting to ttc

My whole life I’ve always been that person that knew they were meant to be a mother. Even through my teenage years, although I was young, I couldn’t help but feel there was something missing! It’s always been hard for me to ignore these feelings and carry on with “normal” things like work and school, but as I get older it keeps getting harder and harder! Now, let me say I’m no where near old, just having turned 20 last month but this wait has felt like an eternity since I’ve been wanting to have a baby since I was 15! I’m in a very committed relationship, he’s 24, and we plan on getting married next year. We talk about having kids regularly, we both like the idea of a large family and want to get started right away! We decided to wait until my 21st birthday to ttc, and now I just have so much baby fever! I know a lot of people might think we are young and have our whole lives ahead of us but my life long dream has always been to be a mother.
