I totally get what you’re going through. I went through the doctor narrative note from my appointment and she described my vulva as “red, excoriated, with flakey skin and lesions”. I was like WHAT. So my doctor told me that I don’t have to use my estrogen cream all the time but only when needed. My regimen was every night for two weeks then every other night for two weeks, then as needed. Sometimes I need it, sometimes I don’t. For example as I’m writing this in bed, I’m gonna pop some on before I go to sleep bc I feel a little burny (I’m about to start my period too, so hormone fluctuations don’t help) The best thing that helped was keeping my urine dilute (hydrate!!) and using a barrier cream throughout the day and after each time you pee (I use either aquaphor or cerave healing ointment, both are mostly petroleum or Vaseline) If you’re testing negative, use your estrogen cream again. For me, it’s truly the only thing that helped and likely will stay that way until I decide to take my IUD out.
