For months I have been having this itching around the opening of my vagina, it's off and on. But when it is on, the skin around my vagina is raw and red and sometimes will bleed when I wipe. My discharge lately is white and thick, and when I look at my vagina the opening usually has a bit of the discharge sitting in it. Idk what to do, do I have a yeast infection? I am not sexually active and I don't use tampons so those factors are out of the picture as well. Also, I started taking birth control in mid December and I have accidentally taken it late for the 0ast few days by like half and hour to an hour, so idk if it is hormonal or anything.
