I Have Only Taken This Medicine Twice. During The Same

I have only taken this medicine twice. During the same time I have had some pain and itching in the vaginal area. I have been to my gyn and she ran a couple of tests. It's not bacterial so I think she just summed it up to a yeast infection. I wondered if this and the meds were related. But going by the list of side effects they don't appear to be. Just thought I'd check.
