I've been on HRT for almost 3 months now, and in the last 2 months I've gained 2 inches in my hips (from 36 to 38), and haven't gained a single pound. I think most of that measurement is from my butt getting bigger though, lol. I've also lost 2 inches in my waist (from 32 to 30), so it's probably just redistributing. I'm 33 and also 5'6" and weigh 140 pounds, how interesting... 😀
