I have a fairly large cyst on my labia majora. It developed about a week ago. It's not an STD as I just got married and my husband and I waited until marriage to have sex; both of us were virgins. I did some internet research and it appears to be a "Bartholin gland cyst." Has anyone had one before? If so, how serious are they? How long did it take for it to go away? Should I see a doctor?
