Is this normal or should I be worried?

So everyday or so I check my weight to be sure that I haven't gained to much. Well I started by checking every week, until I noticed I went from weighing 118 to 125 so then I started checking it more daily. Then I noticed that my weight keeps changing from day to day. At first it was just a few pounds like 118 to 120 but then I noticed that yesterday I weighed 124 and today I weigh 111? I didn't really do much exercise aside from gym class between these but I still don't think I'd lose that much. I also thought about how much I ate and it's pretty much the same amount, no overeating or under eating. Is there something wrong with me?
