Generally speaking, I always weigh myself on my scale three times, and only take the measurement when at least twice it comes up with the same number. Often times the first time is inaccurate, or if I'm off balance, it'll throw it off a few ounces. I always try to step on it the same way, in the same spot, each time. :)
Do remember though that your weight isn't a static number. It'll change as the day progresses, and it's not unusual to see gains/losses of as much as 5-10 lbs in a single 24 hour period! All normal, and not a sign of fat gain/loss.
