vaginapagina | Not sure what is wrong with me

A few months back I had UTI and I don't know if it ever went away or not I felt better for a while but still had a dull pain in the area where i sit down on my left side. This past week it the pain has become a lot worst and I something feel pain under my left rib area . I dont really have burning when i go to the bathroom but I do notice only at night that I get up to use the bathroom a lot
Any one help please. I'm going to the doctors but I want to go next week cause I'm on my period now the pain is bad though
