10 day of water fasting; has anyone else had this happen to them?

I am on Day 10 of water fasting. I have fasted before for 13 days with no issues and dropped exactly 13 pounds.

However, on this fast, I have found that since Sunday, my weight has been shifting between 133 to 135 pounds. It goes up, it goes down, it goes up, it goes down.

The only difference between this fast and the last is that I have been resting a lot and doing stretches.

I have also noticed that I have been slightly gassy.

I am hoping someone could please help with some insight. Is it possible to reach a state of not losing weight and gaining during a Water Fast when not consuming anything at all?

I am not menstruating...nor am I pregnant.

I would like to say that so far I have dropped 11 pounds, but because the weight has been going up and down for 3 days, I guess I have lost between 9-11 pounds....but I really cannot tell....the weight just keeps fluctuating

any information...please help
