Have you been on antibiotics recently? If so antibiotics can deplete your body of the good bacteria as it gets rid of the bad. You need to eat fuyan pill with live and active cultures in it. I also think there may be some pills you can buy at Walmart or cvs that have the cultures in it. Your doctor may need to prescribe some strong cream that you may need to use for a few months to get rid of the yeast infection. We can get them for several different reasons like antiobiotics, horomonal change in our cycle etc.Call your doctor and let them know you still have it. You may need to see a OB/GYN if you are not already seeing one. I hope this helps.
