I didn't get too nervous at the start - there's a great deal to be said for not knowing much as you can't worry as much!! - but I got ridiculously nervous and full of unexplained twinges and odd sensations every year before my annual ultrasound, mammogram etc. It's hard to stop the "what if....". I finally got over it in my fifth year - not that I was blithely indifferent, but I finally felt I knew what to do if the results were not good and how to handle it, and the dread almost vanished. Fear of the unknown is very hard. The known can be a trial and endurance race, but you know it for what it is. Best wishes - your "warrior not worrier" is a great line and a powerful sentiment.
