Hi Christina,
I have my own little theory about that...... not based on anything scientific and maybe totally wrong, but my personal experiences have proven to me that when I become more active, especially spending time out doors I tend to retain a little bit of water.
I think is great that you are not doing this "scale based", but on how you are feeling. Sometimes the scale is not always an accurate gauge for progress. Weight can fluctuate a couple of lbs a day for no apparent reason, but the pant-o-meter (when you take your freshly washed jeans out of the hot dryer and they are getting baggy, you know you have progress. )
You are doing wonderful!
Hugs,
