Hopefully this is the right board - I wasn't really sure where this would fit!
I currently take hormonal birth control (TriNessa, a generic brand of Ortho Tri Cyclen); I use the 28-day version. I've noticed that I generally seem to gradually gain weight (according to the scale, at least) between approximately days 3-26 of the pack, and then drop 2-3+ lbs over the course of the remaining days, with my lowest weight generally occurring on around the first or second day of beginning a new pack. I'm guessing it must have something to due with hormones and water weight, but I do find it kind of strange that my weight loss only seems to be reflected on the scale during one small window of my cycle, and that it's reflected so dramatically and abruptly. Does this sound normal? Any insight/input would be appreciated!
