I know I'm obsessed, bare with me...I weighed 160.3 sunday morning. Today I weighed 162.4 tonight..163.9! It lile I'm gaining steady fast! I started today..could that be the issue or am I in trouble? I mean that's almost 4 lbs! I'm 13 wks out..

Yes, it is TOTALLY conceivable to gain water weight with your TOM. You are also comparing morning weights with evening weights. Definitely going to weigh more in the evening.

Honey, step away from the scale. It's going to make you crazy!

On second thought -- when you ask "am I in trouble?" ....well have you been eating sensibly, exercising, and staying hydrated? If your answers are yes, yes, and yes, then no you're not in trouble. Keep doing all the right things, and the fat loss will happen.

And don't obsess about the scale!!

Throw the 163.9 out. It doesn't count. It looks like the 162 was this morning. Go with that one. Everyone's weight fluctuates throughout the day and we typically weigh a couple pounds more at night than in the morning. That being said, absolutely 4 pounds can be hormonal fluid retention. That is my typical number, though I am much heavier than you. Within a couple days of my period starting, it usually comes off. No reason to panic.

Good luck!

I am a scale addict! All of my life I have weighed more at night than in the am...but for the past two weeks I will stick to a weight all day..all week..then bam lose two lbs. So this gain is out of the norm for me. I have been eating right and drinking my water. So I guess it is fluid. I hope! To gain almost four lbs puts me back in the old frame of mind of panic and failure. I'm going to sleep on it and hope it all is hormonal! Thanks ladies!

Good luck! I'm a scale addict, too. I'm not quite as bad as I used to be, but I would weigh every morning and every night. If I didn't lose 2 pounds overnight I would know, because of the consistency with which the two situations happened together, that I didn't get enough sleep the night before. It's okay to be a scale addict if you are wired that way (Numbers! Charts! Data!!!), you just have to remember to only compare apples to apples, or when you do look at am and pm numbers, you are only looking at them to identify a pattern, not an absolute.

Best wishes from one geek to another!!!
