Teen Pregnantcy

I feel ready to have a child.. I work with kids all day. And I've always known that I've wanted one. I had always planned to wait until I was financially stable and married before I even considered having children. But I'm 16, almost 17 and I'm having second thoughts on that. I just need to hear other peoples thoughts please. I know it's not the smartest decision, but I can't help but want it..
