Reoccuring Yeast Infections

Ladies I’m 17 and I began to have yeast infections in May. I went to the doctor and she prescribed Diflucan. The symptoms never left. I went back to the doctor and she gave me Diflucan 2 day dose and told me to get monistat. I took monistat and for like 4 days I felt normal. Then the symptoms and discharge returned. After that I went to the gyno and they gave me Teraconazole 3 Day Cream. I put it in and it worked for a few days again. and now I’m back to the symptoms and weird discharge again. I don’t know what to do. I’m frustrated because my mom has spent so much money and doesn’t want to take me to the doctor with her. How can I make this go away without telling her? Has anyone gone through this?
