My struggles with HRT made me wish for a hysterectomy at times.
After 5 years since my periods stopped, I think I have now reached a level of comfort. Natural progesterone was a big problem for me. Even with a 1mg estrogen patch, the continuous progesterone at 100mg caused constant bladder/urethral burning and occult blood in urine. It also burned my vulva when urinating. Going off HRT I would improve for several months, then low estrogen symptoms kicked in and vagifem alone was not able to keep VA in check. Hot flashes were mildly there, but the VA was much worse. Back on HRT, I would be fine until the progesterone levels built up (about a mo), then the unremitting bladder burning began. It took a while to realize it was the progesterone....almost 2 yrs!!
I am now on the US version of what I think is Evorel Conti in UK. In the past, I could never tolerate BCPs due to the PMT with norethisterone/norethindrone which made me depressed, fat, etc. I tried the COMBIPATCH (US version) with trepidation, expecting issues and have found none to my surprise after 2 1/2 mo!! The combined tablets did not work for me. I had hot flashes every night and persistent VA even combined with vagifem after a 3 mo trial but NO bladder pain. I researched the blood levels of estrogen and NE in the two available combined patches in US and found that the highest blood levels for estrogen and lowest NE levels are with the combipatch 50/.14 dose and my doctor agreed to prescribe it. Since the NE dose is lower in this one (the other one has .25 NE), there is some propensity for spotting but I have had none of that. The patch sticks very well and I change it twice a week. I have tried it on stomach and hip/buttock, the later of which gives slightly higher blood levels. I like the hip/buttock application better as I think the levels seem more even as I get closer to patch change day. I also leave old patch on for about 6 hrs after applying new patch before removing it. So far I have still been using vagifem also, but I may start to taper off it as it does irritate my parts mildly the day after using it. I also tried 1/2 combipatch with the vagifem and it wasn't enough to keep VA symptoms away.
If you haven't tried this after being post-menopausal for a while, I suggest you give it a go....as I am very glad I did so far. It might just work : )
