Is the scale saying I weigh more because I didn't drink any water yesterday?

I only had a couple cups of milk. I was bad yesterday and had no water ๐Ÿ˜ฌ I weighed more this morning. I thought I'd weigh less because I even pooped before I weighed myself. And I wasn't. The other day I was 3 pounds lighter. ๐Ÿ˜
