Baby Fever

Hey guys! I'm almost 19 and know it is all hormonal, but I have wanted a baby since I can remember. My college degree in my field only takes 2 years and I can start looking for work. How much do babies cost/how much do I have to save? I really want a baby so bad but I know without the money, I can't give birth to my child in safety, nor can I safely say that she will be healthy without the money to properly care for my baby. I am almost positive that I won't have family support so I will only rely on me and my boyfriend. I'm sure this is all just pms or something or hormones but it hurts all the same.
