Turning 19, thinking about TTC, need opinions!

I'm turning 19 this year. Me and my fiancé  have been together for almost 4 years. We have lived together since we were 17. We had our own place for almost a year but he got laid off and we had to move back in with my mom. He has found a new job, but we are not quite ready to start searching for another place of our own. Am I crazy for wanting to try for a baby ? Or should I go for it ?
