Hi AVeryGoodThing, Sure you can gain some water weight during your period while on the MC, but look at one of the bennies of being on the MC! No cramps! Yea! Also, I would guess that you will lose the water weight pretty quickly, since you are not stuffing yourself w/ lots of salty and/or sugary junk.
If you are hungrier, drink an extra glass or 2 of lemonade, and don't forget to keep drinking H2O!
Desiree has probably finished her fast by now, but I still wanted to make a few comments.
I think the timing of starting the fast and the start of your period has something to do with it.
I started the fast a few days after my period and originally intended to do 10 daysâ€”avoiding having my period during the fast. After reading the stages of fasting, I decided to try for a pink tongue (however long that ended up being).
So now I'm on day 21 and this is the last day of my period. I'm anemic and thought I would be dizzy, but not really. I did notice a MUCH lighter flow, brighter colored blood, and some clots released, which is good, I think. I did not experience my usual cramping or cravings.
About the weight gain, my first ten days, I lost nothing and the second ten days, all of a sudden lost weight. I think a half a size, but I wasn't really overweight to start. I heard that the fast will make your weight normalize, so if you're underweight, you gain. I also read that increasing the Maple Syrup can make you gain weight if you want to.
