To address your questions regarding Evoril Conti -
Many do not get on with transdermal patches, they are not the most effective delivery method and the adhesive can be an irritant. From memory, they come in two strengths. Even so, these strengths might not work for all. Many opt for gels and creams as they give the user greater control over the level of hormone and are a more effective delivery system. Dosages tend to be changed if symptoms do not go away - the correct levels a person needs is unique to the individual.
Patches will have little to no effect on vaginal atrophy, ditto creams and gels. Oestrogen that is specifically for atrophy needs to be delivered directly to the vaginal tissue. It is a far lower dose. I disagree with some of the information given on the FOLX site - vaginal pessaries are inserted immediately before one goes to sleep - it will have dissolved by the morning. They do not weaken condoms.
I have been taking HRT since 2018 and at no point ever has anyone looked at my vagina apart from when I have a smear. It was during a smear my suspicions were confirmed that my vagina had atrophied. I told my women's health (private) doctor (who then prescribed Vagifem), something I still use bi-weekly.
Personally, I would recommend talking to a specialist because relying on your GP is a lottery at best - many have no idea about HRT. Maybe start with Louise Newson's website. She specialises in women's health and HRT, so she will have the most up-to-date information. And that's the other issue, there's so little no research, that much of the current information is based on old research/HRT.
