Retention? Glycogen? Help

Jakes231

4 weeks ago I weighed 154. I do not overeat but diet is high in carbs. But I was wondering is that I have constantly been weighing 158 but have not gone over maintenance? Sodium is 1500 to 2000 every nowand than higher, carbs like 360g, but I do not know why I'm stuck at 158, clothes are the same, but scale is still saying I have gained? Is it just my glycogen being at a good level and when I was 154 my glycogen may have been down? I am just confused.
