BV help

So I'm pretty sure I've got BV from my IUD. I thought it may have been a UTI (I've never had either) but my smart bf helped me figure it out.. Now, I don't have insurance and I just started a new job so I don't have much money..I started AZO-Yeast Plus to try it and see if that works..
Has anyone had it and how did you get rid of it?! How long did it take? 
HELP.😫
