Suggest Treatment For Recurrent Bacterial Vaginitis

Hello, I am 29 and experiencing dark, foul-smelling and sticky vaginal discharge. This has been happening for some time. I am being treated for hypothyroidism by an Endocrinologist. I have always had discharge it especially over the past 2 years it has been tinged with blood and my periods are irregular/non-existent. I have been treated for bacterial vaginosis twice in the last year. However, I continue to have symptoms- my Endocrinologist tells me to go see my Gynecologist because it s a reproductive system issue and my Gynecologist tells me to go see my Endocrinologist because it s an endocrine system issue. I have been to both and they both blame the other while I am left continuing to suffer. Politics aside, my Gyno suggested daily probiotic with 2,000 IU vitamin D each day. I ve started that regimen for 9 months with no results. It is extremely embarrassing to have this discharge and I want it to stop. I have had my last Pap smear in late 2015 and thyroid ultrasound in 2015 both with no issues. I am obese (270 lb) and fear my chronic bacterial vaginitis (if that s what it is...) is being caused by bacteria from my urine (I m a little incontinent)? Any suggestions would help or even an idea of how to tackle the issues with my doctors! Thank you for reading
