You definitely should have asked for a leave of absence, and not just dropped out. That was not a very well thought out decision, or you got bad advice.
I agree w/above advice...your best chance would be getting back into Morehouse. The chance of getting into one school, that only has 50 seats, in your home town is not going to be good for anyone. For someone who has already dropped out of school once, it is likely to be harder. I would advise you not to lie about your previous enrollment/matriculation, if you do choose to reapply. And you need to address why it was that you felt being pregnant necessitated dropping out, rather than taking a leave of absence. I wouldn't say you are cooked, but for sure your commitment to medicine is going to be questioned because of what you did. It's only fair and logical. That said, if you can show that you still really want to be a doc, you can do the academics, and that your family/whomever is helping you with the baby is going to be supportive, then med schools may consider you. I still think getting back into Morehouse would be 500% easier than trying to get into another school, though.
