Worst Baby Fever Ever!!!

Guys, I literally have the worst baby fever ever and it's been going on for about 3 years now. I'm young, but everyone says I am super mature for my age. I'm very responsible, not into going out at all, don't drink or party. My mom calls me her 40 year old in a 19 year old body. I'm in a very stable and long term relationship currently. I know this man is the man i want to marry and be the father to my children. He is graduating college next month and already has a very well paying job lined up. I've been thinking a lot lately how it wouldn't be bad at all if I got pregnant. I feel such strong desires to have a little one in my life. I know i'd be such a good mom. I haven't graduated college though but i'm really starting to think I want a baby soon. Am i crazy?
