Are we wrong? 18 & 19 ttc?

Hey everyone,
my fiancé is 19 years old and i am 18. He spoke to me about trying to conceive, he is going into his second year of college (he only goes part time) and is working a part time job that pays 22.60 an hour (his father owns this company and he works 6 hours a day). I have graduated high school but don't really see plans of moving onto college YET because i'm not sure what i want to study yet. I also am working in the same company as he is and am earning $20.60 an hour but i work 9 hours a day. We both have our own home, pay our own cars, insurance bills etc and based on what we have left over he believes that we will have for a baby and more left over. We live in a 4 bedroom single family home so there is space as well. I do believe i am ready to raise a child and also do believe he will be a great father. Are we wrong/too young for this?
