I have been experiencing this white thick discharge for about a year now. There is virtually no odor and sometimes it is really thick or really thin. I thought it was a yeast infection so I went to the gyno and they diagnosed it as one. I was prescribed diflucan and it didn't work. I have also tried just about every brand and length of over the counter yeast infection treatment. NOTHING WORKS. I have no itching or inflammation at all so I think it is something else. Also, I have had 2 sexual partners and practiced safe sex(birth control and condoms) with both of them. I have been tested for STDs and diabetes and it has all come back negative. I have also noticed that the discharge is sour. This makes me very self conscious when it comes to oral sex. sometimes the discharge is so bad that it feels like I wet my pants! I keep reading that it is normal but I also experience some lower back pain and cramping when I am not having my period. I also have polycystic ovaries so I don't know if that has anything to do with it. Please help!!
