Mine is supposed to end within today and tomorrow but the scale reads 2 pounds heavier than yesterday and I haven't been going over my calories. How soon does the water weight tend to go away?
I would think that might vary from person to person. I show a gain of about 3 lbs in the few days right before, and then it's gone by day 2, usually. Don't let this discourage you because I'm sure it's variable.
I gain about 3lbs the day before or the day of my period, and it lasts for up to a week, but usually about 5 days.
