WTH? Does this doctor really have majority of patients who are happy not to be pregnant? Weird comment.
Anyway, I am so very sorry! It is not foolish to hope you are pregnant, ever.... I do know the "getting my hopes up thing" though. I know it too well. I can have my hopes up even while truly not believing I could be pregnant. I have that darned intuition that has said for years I will not get pregnant. And, normally, my intuitions have been right.
