Urinary Issues

My symptoms for began in Jan after a trip. I thought it was a UTI and went to the Dr and was told that my test was negative and that it was probably dehydration. Since then these symptoms of pressure and urinary frequency have come and gone for 9 months. In addition, to these symptoms I have begun to experience urinary incontinence. My medical history includes endometriosis, C-section, and Appendix rupture. I am wondering if these symptoms are related to adhesions or more serious. I was on birth control pills but discontinued use in January when symptoms began.
