What is too young!

I'm 19 20 next week and I'm having baby fever sooooo bad. Normally it's not this bad like I had it before but it was just seeing others kids I never really wanted my own.  but I've went to 3 baby shower in the past month and its starting to hurt that everyone's Having babies. I know I can't afford a baby but I want one so bad. I had a scare and I was so nervoUs but deep down I was excited and hopeful. But after a 5 days my red car finally Got out of rush Hour traffic (what I call AF). But my question is what is too young to have baby fever? I feel like in too young like I have a life ahead of me and how do you get over baby fever?? I can't keep crying myself to sleep.
