Hi doctor i have had what i believe to be a yeast infection for over 3 weeks, i have tried the miconazole otc but nothing. The symptoms resemble those of a yeast infection, the discharge is white with no pungent odor and it seems to have started after i got treated with an antibiotic. I have had a yeast infection before so i automatically assumed it was a yeast infection. I did get tested in september for any stds and it was negative. Thank you in advance.
