Ok...it's my first time so i need some adivice!

okay this is TOTALLY natural. it's nothing to fear... the pain あなた feel is just your monthly cramps. you'll get them around the same time your period comes, it'll hurt. but excersize can ease the pain.

And don't worry about getting your blood druing school... just bring some pads with あなた in your 財布 または bag. If あなた don't happen to have a pad on あなた while you're at school, just roll some tissue and put it in your undies.

If あなた wanna try tampons, I guarantee they don't hurt at all! it just feels kinda weird when あなた put it in. read the directions and follow through, you'll be fine.

it's okay! I was a little afraid when I first got MY period. you'll be alright!
