Worst baby fever ever

Ive always wanted a baby. Even when I was younger, I spoke about it with my friend when I was 12 how I wanted one when I was 21, but even at 15, I always thought about it. Im now 20, almost 21 and have been in a relationship for over 3 years with my SO. I have had the worst baby fever for so long and we have spoken about it. Hes a pro rugby player, so thats a huge thing for him and he says he wants to wait (hes 24) which is totally fair. However, it doesnt change how I feel. Im not someone to get myself pregnant and we are always super careful, but am I wrong for feeling like this? Its all I can think about!
