Definitely stop doing that every day! Weight does fluctuate, could be due to water weight, food you currently have in your gut, hormones, etc. Once every 2 weeks is good.
Even if you don't lose weight for a week or two, if you are doing all the right things, don't worry about it. Could be that you are turning fat into muscle. Muscle weighs more, so you might hit a weight platue, but in the long run that muscle will burn more calories and you'll continue to get into better shape.
