Lost 2 Pounds.. or no pounds

I'm not really sure if I lost any weight or not when I weighed this morning.  I got on the scale prior to my workout and my weight was the same as it was on Friday.  I worked out, got my shower, and weighed again on my way out the door.  Oddly enough, it showed a 2-pound drop in weight.  So, I'm a little confused if I lost 2 pounds or nothing at all.  
Either way, I'm dropping in size.  I had my monthly Masonic business meeting last night.  One of my brothers asked me how much weight had I lost.  Always a good question to hear.  My dress belt was even fitting looser, so I had to take it up a notch.  
Regardless of what weight I go with, the results are visible in both body size and body weight.  I'm still lighter than I was and I'm going to be lighter than I am.  I'm going to say I'm at 333, and take the 2-pound loss for no other reason than to keep me motivated.
