What should I do?

I’m a 19M that lives in Texas I’m a soon to be father and I don’t know what or where to look for a job that can help me support my girlfriend and future baby. As of now I work at an ac and heat company 35 hrs a week average 10$ an hour as a helper. It’s okay now I can live semi comfortably but that’s not going to cut it for long. I know I can grow eventually in this field but I need the income now or soon, I don’t want to put stress on both of us worrying about if we can pay rent or get the baby what he/she needs. I’m just worried at this point I’m thinking or getting a minimum wage job as a 2nd job. Could anyone help me out with some advice on what to do. Sorry for any grammar issues or anything else... I’ll be responsive thank you!
