Considering Dating a pregnant girl, please help?

Love her and take care of her. If you want to be with her go for it. But be ready. It won't be easy. In the end, her and that child will love you more than you could ever imagine. Loving someone when they are down is true love and she will feel that. What a great story to tell down the line when you are both old and grandparents. If it were mere pity or charity you wouldn't be attracted, simply willing to help.
