Urinary and Bladder Symptoms progressed

I had two UTIs 2yrs ago, they were treated but i still didnt feel right, felt like i had to wee but when i did little came out and i was never left feeling fully empty. Experiencing this discomfort, i went back to the doctors, she took tests and told me there was nothing wrong i just needed to retrain my bladder. I suffered from this discomfort for a yr, trying to retrain my bladder. Symptoms progressed to vaginal sensitivity, spasms and lower abdominal discomfort and i struggled to find a position comfortable to lay/sit in. Out of nowhere, it dissapeared, i still suffered with a more sensitive bladder than usual but it was a relief to be rid of the discomfort. Days ago, after a year of being free of it, it returned at the same time as my period which coincidently was what used to worsen my symptoms before. I cant put my finger on whether the symptoms stem from my bladder or vagina now, it could all just be psychological? i'm 16, there is no pain, but i can't deal with it anymore.
