So I got tested for a uti and it was negative. I went to the doctor and they don’t believe I have a yeast infection or any kind of vagina infection based on my symptoms. I just got off my period a few days ago and it’s been a week of having this lower back discomfort, some mild pelvic and abdominal pain. The discomfort and pain arent bad at all but I’m just tired of dealing with it and ibuprofen hasn’t helped. Any ideas?
