Hi Leesha, first it could be one of three things, 1 trichomoniasis, 2 gardnerella or 3 BV bacterial vaginosis, so 3 things to get tested for, but in the mean time you could try drinking up to 8 glass's of good minral water a day, and start drinking cranberry juice, it will help cleanse your systom.
Good Luck
Do u have a poor diet because that could be the main cause here!
