Some period questions!? please help me!?!?

Ok...No weight doesn't matter at all, You might be on your period on vacation but don't worry im going to florida in 4 days and im sure ill be on mine so your not alone and im 13 too! if your mom doesn't know you even have your period yet you need to tell her so she can buy you stuff, You can try sneaking a tampon but they will find it in the trash can unless you wrap it in toilet paper and hide it, #3 no it doesn't have anything to do with it the time between periods vary it depends on your body.
