Madison I weigh everyday and have pretty much for years, I have a calendar that sits on my dresser where I log in my weight, I usually compare week to week, like what I weighed on Tuesday this week to Tuesday last week, so I don't get crazy about it.
Anyway, what my long ramble was meant to say was I used to gain 2 pounds day one of TOM without fail, now it isn't that structured, but if you're weighing daily, if you keep track of That as well, I just put sp on the day it shows up, then you'll know what your particular pattern is.
Best of luck to you
