Why did I gain?

Hi All! I just started Cycle 1 on Friday and have 10 lbs total to lose. I've stuck to it perfectly, without even a bite of food outside of the diet. in the first 3 days I lost 3 lbs, but I got on the scale this morning and gained a pound back. It's a bit discouraging. Has anyone lost a lot on cycle 1? Will it still work if I only have 10 to lose? Thanks so much!
