@duran75a, It is my experience and understanding that by doing all of the healthy things now, that you are giving your body the best opportunity for success. I commend you for your positive attitude, too.
I would suggest that you start making a list of questions for the doctor when you have your appointment. Write it down, and take it with you.
Is someone going with you? It has always been helpful for me to have a second set of ears. When I'm nervous. like in an appointment, I don't remember anything.
