I had a yeast infection a month ago and from time to time, I get ...

This will be my third month in taking the Loestrin 24 fe... and OMG.... since June... I have nothing but vaginal issues. Discharge which is clear to white... itchy outer vagina, irritation. I've gone to the OBGYN and have been tested for STD's several times... and each time is negative. I've been told I've had yeast infections... and have been treated for them... But its constant. Everyday I drink canberry juice, take acidophilus vitamins, eat 2 yogurts a day...I still have issues.
