Check your scale for consistency

I get t on the scale this morning and was up a pound from what I was yesterday and it was very unexpected and frustrating. I had some constipation that resolved itself yesterday and I hadn't eaten much yesterday and also pooped this morning before getting on the scale. How in the world could it have gone up?!? Discouraged, I got back on the scale and was down 2.5lbs from the first reading!! I weighed myself a couple more times and they were all about the same as the second reading I had gotten. Moral of the story, if your scale number doesn't make sense or you have a large spike/drop, hop back on and make sure the results are consistent.
