question

so I have this uncomfortable feeling when I use the restroom.. not burning or painful just uncomfortable. It usually comes a week before my period. has a different color, smells sometimes and kinda sticks around for a week. I went to urgent care because it has been going on for 4 months or so. It was around Christmas so my ob wasn't available. ran a test for a UTI and it was negative. She couldn't tell me anything else.. But thst I had a small infection. gave me a medication for 7 days. well.. it's back. not close to my period this time. Any ideas or suggestions on what it sounds like? I do plan on making am appointment with my ob. But it's just weird that it happens so often.
