I'm positive that you can have both your baby AND a career. I'm not saying it will be easy, but you can do anything you set your mind to. Plus, all of us girls will always be here to talk when you need help or advice or just plain feel like you can't do it.
My mother was 17 when she became pregnant with me, and ended up not finishing highschool. But later on she went on to finish college, get a great job, and her and my dad (not the biological one, someone even better) are now in the process of starting their own business. It wasn't easy, and it took a lot of hard work, but she did it. And you can too. I know it.
You can do it girl!
