Girls First Periods Dear BeingGirl Experts, I am 13 years old and just got my period. My mother has no clue. I feel I should tell her because I feel that if I don't, one day I'll go to college and she'll think I still haven't gotten my period. How should I tell her? Faith --- Dear Faith, I've always thought telling your mom face-to-face is the way to go. Just sit down with her at the kitchen table and say, "Mom and I just wanted you to know I got my period." You might ask her advice on feminine protection, or let her know you have it under control if that's the case. If you don't feel you can tell her face-to-face, try writing her a note and leaving it in a place where only she will find it, like her purse or her underwear drawer. Or you could go shopping with her and casually toss a box of your favorite menstrual protection into the cart. Remember, your mom got her first period once too! She remembers what starting your period is like and will want to be a part of this exciting time. It's a natural part of female development.
