Any one have days where they feel & look not as big?

I don't know why but today I got up & I don't feel or look as big as I usually do. I've been eating really good this whole week like I've only eaten out once this whole week. Could it have something to do with the fact I'm eating better? So not too much bloat is happening? The one on the left was at 23 weeks 5 days. The one on the right, this morning at 24weeks 1 day.
