i got mine last year at my birthday party!!!! i had just turned thirteen! i was like WHY NOW!?! but afterwards, it's not that bad. i just hate the cramps! if you have bad cramps, take a pain reliever like Midol. it really helps. Also, you gotta ask your mom about what age she was when she got hers cuz my mom was 13, too. she even knew i would get mine soon! I hope this helps.
