Gaining a lot weight during period

Hey guys, just wanted to check if this is just a me issue, or if it’s like common i guess. lol

I usually wear a size 4 in jeans comfortably, but when i’m on my period I go from a 4 to a 6/8. While my physical appearance doesn’t change much and even if it did I wouldn’t care all that much. But, it causes a lot of discomfort and also makes it so much more difficult to find outfits to wear haha. anyone else deal with this? if so have you done anything that helps?
