Dec.Angel, if you check out old posts here, you will find out that large losses at first are not uncommon. I lost 14# the first week, and decided to stay off the scale for awhile, and rather go by my measurements... and I lost 15" on them in the first 10 days!
Getting on the scale too much is not the best idea, because as Deb said, your weight can fluctuate so much in a day's time due to food eaten, food eliminated, water consumption, water eliminated, salt... TOM for women, and much more.
