Do you weigh in during your period?

Nope. Since I know exactly what my mood is like during that week, why would I make it worse by seeing my weight go up? :P
I wait until near the end, which is usually where my weight goes back to normal, and then I start weighing myself daily again.

It is just water, don't worry that you are failing.. I weigh in because I get my "TOM" every two weeks. So you can imagine- .5 here, 4 pounds there. It's really irritating. The weight loss over a bigger span of time is what really counts.

Ditto to everyone!! My weigh in was Wed but the scale was seriously high due to this and I knew it so I waited 2 more days and I lost another 4lbs from last weeks normal Wed weigh in---I may weigh again this weekend or better yet wait till Wed next week and see if it changes more once it is well past TOM--which on this stupid BC shot is whenever it feels like it so if I were to have a normal TOM I might weigh less--who knows--going on a new BC the first of the year---fingers crossed this crazy schedule for my TOM ends !!

yep! i do it everyday actually but yes! i want to know how much water weight i gain

I joined MFP about a month and a half ago and I had gained weight the week before my period.. I was so discouraged because it was my first period while using MFP and didn't know I could gain that much. I ended up losing around 3-4 pounds of water weight once I was done with my period. Cheer up... the scale shouldn't be your only source of reassurance

Forgot to answer your question LOL... I do weight myself but I don't obsess over it, just for curiosity purposes

I thought this article had a helpful tip for weighing while having water retention

Trying to measure fat or weight loss in women on a week to week basis is often a futile endeavor and females may have to measure only once per month (ideally at the same point in the cycle) to get any sort of consistent or comparative measures. Women should generally pick a specific point in their cycle and make all measurements then to track changes month to month.

Another option is to measure weekly but only compare the same week of the cycle each month. So week 1 of the cycle would be compared to week 1 of the cycle a month down the road, week 2 is compared to week 2, you get the idea. What doesn’t work is comparing week 1 to week 3 because the body may be holding a ton of water during one of the weeks and not during the other making comparison impossible.

It was hard for me to break the habit of weighing in everyday. All it did was add stress to my life! I have now eased back to weigh in once a week, before ingesting anything, nearly or completely naked first thing in the morning. If it is during period week, I will almost always shrug and know it is PMS gain like water retention that isn't normally the case otherwise. Quit driving yourself crazy with a move on the scale! It's NOT healthy!! :flowerforyou:

I stopped retaining water at any given time during the month when I cut out grains, sugars, legumes, and milk. (carbs make the body retain sodium and water). I'm Primal so I follow a no-grain/milk/beans - moderate protein - high fat lifestyle. I also stay far away from processed food products. (Not 100% - I do not deprive myself)

Even during TOM. My PMS junk carb cravings are fading. If I give in to them I will retain some water but once I start I lose all interest in the junk and my weight drops back to normal.

I haven't been a member long enough yet to know if I'm going to weigh-in during it or not, haha!
