Hi, I was told by numerous doctors I had an over active bladder. I was basically told that I was too young for it to be a symptom of low estrogen. For me frequency was my first symptom of what I now know is the peri stage. My frequency is so bad I often feel I need to go again within a few minutes of going. It drives me crazy, sometimes I dread going out. I only ever go to places where I know for certain there is a toilet.
The ovestin cream is the only vaginal estrogen I can tolerate. Many others on this site use vagifem which does seem well tolerated by most. The other thing I tried which really helped was the estrogel (a gel which is rubbed into the skin). Sometimes I could not feel the urge to go for nearly an hour. It also helped with anxiety. Because I am still having periods, I just reduced the amount of gel used to enable a period. During this time my symptoms would increase big time and my doctor was not happy with me using it like this and so she suggested the BCP which contains higher levels of estrogen. However I feel like I have gone backwards as the frequency is back with vengeance, I think its due to the levels of progesterone as that's known to aggravate the bladder.
I am hoping I have not confused you, just wanted to give you an idea of what I was trying.
My thoughts would be that if you were to consider HRT for your other symptoms you may well find your bladder improves as well.
Using the birth control pill has made me sleep better and reduced the aches in my hips (so I definitely need the extra oestrogen, just not so much progesterone I guess!).
I keep searching for answers, there has to be hope for us out there xx
