Am I the only one TTC this early?

Sarah💚
Hello everyone!
I'm 23 and my fiancé is 26. We are getting married this June and I couldn't be more excited to marry him! We decided to start TTC already. Both our parents had difficult times conceiving so we wanted to start trying right away! 
Are we the only ones who started trying before the big day? I'm still so new to all this. I don't have any friends my age going through it.
