My Mom Told Me That I Have Perforations Down There.

My mom told me that i have perforations down there. She said when i was little i got sick, and they brought me to the doctor. They did a checkup, and found holes. She is in school to be a nurse. She thought it wouldnt effect me until i have sex, but she found out that it could make me have a lighter period, with more cramps. I am 14, a virgin. My period is very heavy, and eight days long, and very painful.
