Hi Peri2022
You say you don't get VA symptoms the rest of the month but are you using any topical vaginal oestrogen at all? It may well be that your V tissues are thin and are sensitive to the Utro even though fine at other times?
Also - is the burning and itching on the inside or mainly around the labia and entrance to the vagina?
I always get itching and irritation when I use Utro - every single month. Labia and around the entrance. I use a variety of things to relieve it and/or provide a barrier. I do use local oestrogen nornall but in turn I either apply: E45 cream as moisturiser to external areas, and entrance to V, or Vaseline as barrier to labia to prevent the prog goo touching the skin, or 0.01% estriol cream which I have as back-up as my vaginal oestrogen (thoigh usually using vagifem/Vagirux). So just a few options to try. I've never used any of the proprietary V moisturisers so can;t comment here but E45 is very inert as is vaseline.
Re using Utro as a pessary - it is not designed to be used as such, and it would need to be used at the licensed dose since theoretically is not going straight to where it is needed as it has to be absorbed into the bloodstream before being transported to the uterus - notwithstanding sheila99's personal experience of this.
Also depends on your bowel habit too I would suggest. Why I say this is that on the morning visit

it may well all be excreted out - when I used cyclogest rectally it certainly had a dramatic effect in that area

!!! When the utro is used vaginally I read in a paper about absoprtion etc, that some of it is "held" at the uterus so some of it lingers a bit longer than one would expect after stopping taking it, whereas as above, in the rectum - it could be likely all pooped out the next morning....
Personally I hated taking it rectally but that's me....
Used like this (Utro rectally) would be very much off-piste so to speak as no research on this unless I've missed something
