The Scale=Discouragment

So for the past 60+ days I went back to using "my fitness pal".  I decided my food handling was getting out of hand and I wanted to see what I was really eating.  A couple of weeks into summer vacation, I started really exercising more.  Two classes on Monday, two on Tuesday, and one on Thursday.  I also picked two other days to run.  Late July, I had to drop one of the Tuesday classes only because of my work schedule.  Today I continue to do 2 classes on Monday, one on Tuesday and one on Thursday and sometimes one on Wednesday.  I also run on Fridays and if I don't do a class on Wednesday I run then (or I try to fit in another one on the weekend).
     So after plugging in my numbers on my current weight and what I wanted to weigh etc  my fitness pal will give me the calories I need to eat per day.  Of course I get extra if I exercise, but it calculates all of that for me.  I would say 95% of the time I am in my range, except if there is a special event or we go out to eat.  My Fitness Pal always says....."if every day were like today, you would weigh ---- in 5 weeks".  I didn't weigh for 5 weeks and to my surprise, the scale had not moved.  What?  Are you kidding me?  Here I am at 60+ days and I might be down 2 pounds.  Talk about discouraging.  (Remember that I had gained some extra weight in the fall and around the holidays and did not get serious about taking it off until June).  I even measured myself thinking I maybe had lost inches from my previous MFP entries and to my surprise, they had not moved either.  I know people say you can't measure yourself by the scale.  In fact, I have one instructor who never weighs herself.  I'm not sure what I am doing wrong as I am exercising 5-6 hours a week plus staying within calorie limits, but it sure is discouraging that I should weigh "blah blah blah".  I will continue working out and I will keep logging in my food and maybe someday my work will pay off.
