Am I ready?

I know deciding if I’m ready or not is my choice, but I like to have some outside opinions on my situation. I’m 19 years old, and just yesterday found out I am 5 weeks pregnant. Of course my emotions and thoughts are all over the place. My first thought was terminating because I think I’m too young. But so many women have children young, it happens. I have an okay job at the moment, I’m in school, plenty of women get through school with children, I have a very supportive family, and a roof over my head. But something is still telling me I should rethink keeping my baby. I don’t want to make a choice I’ll regret.
