The reason I asked if you felt any difference the month is that some of the patches are solely oestrogen, and others are a combination of both oestrogen and progesterone. It was something the specialist I saw asked me about when I told her I had initially been prescribed Everol Sequi. And yes, for me, I found my issues were worse during the first part of the month when I was using the oestrogen only patch.
What is most interesting about perimenopause is that for many, it is plummeting progesterone levels that are causing all the issues - issues that are also caused by declining oestrogen. But because we are told that it's all about declining levels of oestrogen, the progesterone or lack of, is often overlooked. When GPs are looking at bloods, it's usually oestrogen levels they're concentrating on. This is what happened to me and many others, and when we're prescribed oestrogen, things get worse rather than better. (Interestingly, had I listened to advice on the Menopause boards on here, I would have been told to increase my dose of oestrogen which would have made everything worse.) For me, I only needed progesterone and once we got the dose right, every symptoms disappeared within a few days.
As I said many posts ago, HRT can take time to get right. I know once I saw a specialist, the dosage was tweaked twice initially in the first few weeks and all was great for about 18 months. Then I thought I had something I termed lockdown fatigue - low mood, brain fog, extreme tiredness and inability to sleep, but then many of my stranger symptoms returned and I called my doctor who did some more bloods and I wasn't producing any oestrogen at all (although my progesterone levels were wonderful!). She added in testosterone and oestrogen, and it took another few goes to find the right level of oestrogen for me. Even now I'm post-menopause and produce no oestrogen at all, I'm still on the lowest dose because anything higher make all the horrid symptoms return.
But, back to you. I really do feel that your vagina is the most important thing to address. This can definitely be resolved independently and why there are separate topical doses of oestrogen. Given everything you've been through so far, I strongly recommend you trial Vagifem which your GP will prescribe for you. As for HRT, now you know Everol isn't working for you, move on to the next combination. On a positive note, it really can't get worse for you and I feel strongly that once you can control your own dosing levels, you will find the right balance.
Apologies for rather hijacking the thread, I'm just so conscious of my experience and nightmare with Everol that I hate anyone suffering similarly. I have only become so knowledgeable because of the failures by the GPs I saw prompted me to do a lot of my own research. And of course, seeing a specialist was enormously helpful because she explained everything in detail - she understood and was interested in women's health in a way none of the GPs I saw had been.
I really do hope you're able to find a way forward, and do let us know how you get on.
