Who should I tell....?!

sooner or later you will AT LEAST have to tell your mom. after all, you will need someone to buy feminine supplies for you. maybe just beg her to not tell everyone. tell her it is a personal thing and even admit you were scared to come to her for advice BECAUSE of the fear of her telling. i'm sure she'll understand how important it is for it to be kept between you two. i'm a mommy and i know i would want my child to be able to come to me for anything and feel comfortable.

i was 10 in a half. my friend was over when i start i screamed for my friend and she told my mom lol i have a extreamly close relationship with my mom i seriously don't think she would tell anyone something like this i would just go to her and advenually she will have to buy you supplies so just go get her and be like mom i need to talk to you and she say okay and you be like swear your not going to tell anyone and she say yes then tell her thats the way too do it hope this helps ...

Tell your mom, and ask her not to discuss it w/her friends....she probably will anyway....but so what? They aren't going to make fun of you or ridicule you in any way. It's just what mothers talk about w/their friends. She will get you what you need and answer your questions.

ok
so you can just tell it to your mom only mom and tell her that not to tell anyone whom you are not comfortable with
and besides if your friends are also getting periods then you can tell to them

Tell your friend (girl) who is older than you.

You think? You'd know, there's a LOT of blood.
