What great news for you! I could never tell.... I drink a lot of water - it's still 100 degrees outside during the day! -- I only weigh myself in the morning, wearing the same thing, and after I use the potty. That way I get a clean weight without anything to throw it off every day. When I do my weigh in later in the day - after work at the doctors office, I've always gained 2-3 lbs. but it is always off when I use my scale in the AM.
