Someone please help

The past few weeks after I’ve passed a bowl movement I wipe completely until the paper is clean, but then when I go pee a few hours later I’ll wipe my ass just to check and there is more poop on the paper even if I didn’t go. Then today I realized I had discharge coming from my anus a yellow whitish color on my underwear. I’m also being treated for BV for the FIFTH time so if anyone could PLEASE help me find ways to get rid of BV for good I feel so dirty.
