A Fluke or Fact?

I have lost about 3 pounds in the past 2.5 weeks!!!! I'm so incredibly thrilled, but I'm also hesitant to believe that it's true fat loss. It could simply be a fluke, so I'm trying not to get too excited by it, but the number on the scale has been lower than it has been in quite some time!
Even with my body normally fluctuating about 2-5 pounds, my weight has stayed consistent for the past several days, so I'm excited about it! I hope it continues!
