Did I really gain 7 pounds in 3 days? 😟

Okay 3 days ago i weighed myself in the morning and i was at 229.6lbs.....I just weighed myself and the scale says I've gone up all the way to 236 lbs....I have no idea how that could happen. I haven't been pigging out at all. I did have dinner at a Chinese restaurant yesterday, but i also walked a bunch during these 3 days. Is this just water retention or did i really gain all that weight? πŸ˜“πŸ˜“πŸ˜“πŸ˜“πŸ˜“πŸ˜“
