vaginal irritation for two months help

Having vaginal irritation, discharge and urinating a lot. I had a uti back in July and after the antibiotic I was still having same symptoms. I went back to doc and they said I was clear and only had a very small amount of white blood cells and blood but they gave me vaginal antibiotics for vb. It also did nothing. I then decided to take monistat 3day treatment thinking it was a yeast infection. Still not better. I saw my obgyn when I had the uti and they did a routine pap and said everything was fine. I’m NOT sexually active and NEVER have so it’s not a sexual infection. Any advice because I’m tired of being extremely bloated, and irritated down there 😞
