Hello I would like to know if I have a yeast infection or something else. I have soreness to touch and during intercourse and itching and burning on the outside of my vagina. Also, I have just gotten my period again this month. It is not a complete one but for the past three days I have had either brownish blood and just yesterday some red blood. I also have been on the pill for 5 years or so and did not do a great job taking it during the last few weeks.
