I've read about the dreaded plateau's, usually people who have lost a good amount of weight and their body is adjusting. I never thought it would happen to me, I only overall wanted to lose about 40lbs.

I lost 20 lbs, boy was I happy! Then..hmm what happened? I had a bad month and now overwall I've only lost ten. And now I cant seem to lose, I can fluctuate between 5lbs but no further. Is this my plateau AFTER gaining weight?

Plateaus can happen at any time, doesn't matter if you are going up or down on the scale.

Try shaking things up with your program.
