u should be totally comfortable when telling ur mom about ur first period. just tell her wut happened and tell her u need some pads. me and my mom hav codewords for asking for pads around my brothers and my dad at home
however, if u and ur mom dont exactly hav a good relationship and u feel like u definatly cant ask her, u should ask another female relativ u feel closer 2. perhaps a sister if u hav 1 or a cousin or u can also ask a close friend. and if u feel comfortable and confident enough, u can even ask a teacher u can trust. they can definatly help u 2. hope this helped
