Hi
I have always worn my Estradot patches on the top of my butt cheek. When I did try my tummy, the patch came off after only a day.
I also use Lenzetto spray (I’m a poor absorber)- I find the patches give me a low consistent level, whilst the spray raises the level to help my symptoms.
For me the spray alone wore off after about 7 hours so I didn’t get sufficient symptom relief and I had headaches from the fluctuating level.
It is a bit trial and error finding something that works x
