I Have Had A Probably For About 3 Months, Itching

I have had a probably for about 3 months, itching in the vagina discharge is creamy and sometimes looks like glue. I have a odor that isn't fishy, it's just a strong smell that isn't usual. I went to the hospital several times because I do t have a doc. I was told one time I had a yeast infection, the treatment didn't work. Then I went again I was told I had a bacterial infection and they gave me metro pills. Then that didn't work. I went again they gave me a stronger pill which was the same but stronger for another week which didn't work. I did home remedies like eating yogurt, taking vinegar baths. That didn't work. Then I went again and they said I had vaginitis and they gave me medicine that is inserted in the vagina for 7 days which was like 100 dollars, that didn't work. Now I'm stuck like what can I do. What is the problem? What's wrong with me?
