I think I’m going crazy

So I may or may not be pregnant I have taken test and they are all negative, but I’m craving weird stuff that I normally don’t eat and everyone says I have gained some weight in the front and that I “act pregnant” whatever that means. I just got off my depo shot but I have been off it before and haven’t acted like this ? So idk I want a baby but idk and I’m not trying to get my hopes up. I guess the best I could do is just wait and test and see. I won’t stress or anything I just needed to get this off my chest lol .
