Bacterial Vag

I’ve had symptoms of BV since August of last year, I’ve tried rounds of antibiotics provided by my regular doctor, my OBGYN is too costly to keep going back to especially when all they tell me is nothing is wrong. It all started after I got on the pill after having been on the shot, I’m on IUD now but it’s still there. I’ve also tried probiotics and suppositories, but it comes back each time after I stop the treatment. It is now very thick discharge in big mucus like clumps with white stripes in it. I have honestly no idea what else to do to get rid of it, any ideas ladies? Getting desperate.
