Okay so I noticed I had a yeast infection 4 days ago so I got Monistat 1... I used it that night and I was fine... normal reaction and I didn't itch or hurt down there. Well I used it right before my period and I had some light spotting which I'm guessing it was the medicine. Then I got my period which was maybe a day early... I feel feel fine... looks like the medicine is working. Still in my period.. been cramping and what not... but is it actually working or is it just because I'm on my period?
