Pregnant at 20.

Well, I found out I was pregnant 2 weeks ago. I went to my doctor & they also confirmed it. While I am in a stable relationship, have a full time job with great benefits, and a home with the father of the child, I am worried. I am still in school pursuing a career that I have dreamed of having since I was a child. Boyfriend is on board with whatever decision I make. Mind you, he is 24, so he is old enough to raise a child. My parents on the other hand, think I should abort it. Has anyone ever gotten pregnant at 20, unexpectedly? How did you handle it? Any advice would be great. I have so many thoughts going through my mind.
