Hello. help pls

I have been have very very frequent urination. (6 times i wake up during the night and from about 6-8am ill have gone about 20 times WITH HAVING NOT DRANK ANY FLUIDS TO MAKE ME GO THAT MUCH. no joke.) i have been this way since April. gone to the er multiple times, they X out Diabetes, Uti, and couldn't find anything. Even took ultra sound of my kidneys and bladder the last time I went. My primary cant find anything. I went to my Obgyn and got a full examination which came back clean. Now I have requested a referral for a Urologist but that appointment is July 16th. I have been this way since April (End of January, really, but April us when it was beginning to worsen and affect me in the mornings not only the night) So im waiting patiently for the 16th where the urologist would need to do a cystoscopy to check in my bladder.

Does anyone know of this condition or of someone who struggled? please and thank you very much
