Baby fever at 18

I've been with my boyfriend for 2.5 years and I'm hardcore having baby fever. I wouldn't intentionally go out and get pregnant right now, but I really want a baby. I'm going to college in the fall and I'm hoping that will help take my mind off of it. I've been looking forward to being a mom since I was little. 
We've had a few scares here and there and there was such a large part of me that really was hoping for the test to be positive. 
Did anyone else go through this where already at 18 you're feeling incomplete and wanting to have a little one? If so, what helped distract you?
