I’m on the .1 estradiol patch, its not tiny.. you can find the tegaderm here, I cut them in half and they have been a lifesaver

3M Health Care 1624W Tegaderm Film Dressing, Frame Style, 2.75" Length x 2.375" Width, Transparent (Pack of 100) https://www.amazon.com/dp/B000O5YRPU/ref=cm_sw_r_cp_api_glt_fabc_JPXXR6FZ56YJQ0W59X1F

That's great news. I hope it goes well for you. When or if it's time to buy more Tegaderm I recommend the size that's just a bit wider than the adhesive on the sensor so you don't have to do any cutting.
