Bacterial vaginosis

So after my last period ended I started having a problem with excessive discharge (like soak through my underwear and pants) all day and it has this just gross smell. Well I've been treating it with home remedies like probiotics and what not but nothing seems to be working at all. Well now I'm a month in and still struggling.im so embarrassed about the whole thing I'm at a loss. Well today I started my period and I went to put in my cup and It was just a sudden excruciating pain and taking the cup out is 10x worse. So I'm at my breaking point and am going to urgent care tomorrow due to the fear of it actually being something worse and to try and elevate this pain. Has anyone else had this issue ? I'm just at a loss
