Probably 5 lbs but idk because I've never weighed myself while on AF. Well I weighed myself today and I'm on the last day of it. I weigh 176. I won't weigh in again until next Friday.
Oh, so it's not just me! :) I think I weight about 3-4 Lbs more than usual...
4 but I don't have that friend every month only 3 times a year and no B.C.
