Every time i weigh myself it has said i weigh less but recently i have my period after not having it awhile because of birth control and i have noticed instead of losing weight im gaining and losing the same 2 pounds. i guess thats probably normal but my question is when my period is gone will the extra 2 pounds and maybe the weight i havent lost since being on my period kind of suddenly go away or does having your period make you gain water weight and halt weight loss for that week?. ive been sticking to the same calories etc so nothing else could really be affecting my weight.
