Hi kc2021, reference the patch under tight clothing, it's mainly around waist bands due to rubbing can make the patch come loose so if you place it away from them it should stay put, and put higher up on the bottom you won't sitting on it, I was on everol patches for 3 years and put them on my hip, I use estrogel now, but lots use them on the bottom with no problem, can't help with the utrogestan as I use estrogen only due to hysterectomy, but I'm sure someone will advise you on that soon, good luck hope the hrt goes well for you.
