Do I have BV

I went to urgent care like 3 weeks ago because after treating UP I was still having green discharge and burning they tested me and swabbed me my results came back for bv and then I went to my gyno last week, mind you the night before I had sex and I was using boric acid 2 nights prior idk if that played in role in this I told her to test me for BV because of my green discharge and my results came back today negative for Bv and UP now idk who to believe I’m starting to think the test results are wrong I’m still experiencing green discharge and my lower back hurts very much. They told me to do sitz bath and that they can’t help me and that sex does not cause the results to come back wrong.
