stay at home Mommy

Alright, I'm 27 weeks along in my first pregnancy. I'm also 18 years old.  I work at a bridal store, currently, and my fiancé has a steady job. But together, we don't make enough & im worrying. I want to start college in the spring, around the same time I'm due, actually. I want to find a stay at home job that actually pays well. Any stay at home mommies that can help me? Thank you!
