Having a child is a beautiful journey, but it is very hard work. Sleep deprivation, anxiety if they are sick, worrying how you're going to keep the electric on if you're income doesn't give you a choice it's rent or food. I strongly suggest you finish school and have a huge nest egg as well as solid work before you bring someone else in this world. Children are demanding, far more demanding then you can imagine, being a mother isn't just the good times, then you give the kid back to whomever do you're own thing. it's alot of tears,
physical and mental pain and you don't get to say no when you want 2 minutes of quiet. I strongly believe most teen moms would suggest you wait, I'm positive you're mother had tons of help and if she didnt I'm sure she'd pursaude you to mature a bit more mentally and emotionally before bringing another human life into the world. best of luck to you.
