I gain 2-3 pounds each and every month starting about 2 days before until about 2 days into it. If you think it will bother you to see the scale move up, then don't get on there.

It is kind of nice to know though, if you are one of the people who gain. That way, when it happens to you each month you get used to the idea and don't freak out. It used to freak me out until I noticed the pattern. Just don't forget that it will go away in a couple of days.
