natural cures for yeast infections??

Michelle
Hello! I was diagnosed with a yeast infection a week ago. The doctor said there was a lot of it. I just finished a round of monistat 7 but the symptoms are still going strong. 
Any advice? I just learned yesterday to cut sugar and bread out of my diet... and I'm thinking of trying ACV baths, hydrogen peroxide rinces or coconut oil/tea tree suppositories, but I'm unsure how safe these are during pregnancy? Or should I just take another round of Monistat?
