Lost or Not?

So I have a new dilemma.  I weighed myself this morning about the same time I usually do.  It yielded me 2 lbs lost.  I weighed myself again about an hour later and it only gave me a pound off.  So, did I really lose the 2 lbs?  I think I am going to stick with that number because it is around the time I would usually do it.  And in my readings, it is important to weigh yourself about the same time each time.  Either way, I am a pound or so away from my first 10 lbs gone!  This doesn't mean I get to slack, just more motivation to keep going!
