girls, an intimate question?. Something has come out from the outside of my vagina, it doesn't really hurt and I don't notice it when walking and so on, I just noticed it when I was inserting Utrogestan. It hurts when you touch it, it's slightly swollen. I insert Utrogestan vaginally twice a day — it was prescribed because of a threatened miscarriage, and I've been using it for 3 weeks. What can I rinse it with or apply to it?
