Up front: I am not a doctor.
Seriously, seek a second opinion, and if you are a woman, and it sounds like the original doctor is a man, find a woman doctor. I know this sounds sexist, and I’m honestly not trying to be, but it has been shown many times how male doctors tend to overlook or not listen to female patients. You must advocate for yourself.
Anecdotally, my spouse has had this happen numerous times. And it is extremely frustrating every time because it’s effectively a waste of time and money. And, something could be seriously wrong (not saying anything actually is), so you should make very certain at minimum that certain testing is done such as various tests from blood work and/or urine testing.
