help! please? i just started my period.. im pretty sure, theres blood in my underwear, anyways, i put a pad on and theres NO blood or anything. its been in for like 2 hours... i also need tips about my period. where can i hide pads/tampons when i take them to school? how much should i bleed? do i change a pad after 6-8 hours even if theres only a little blood? and any other things i should know... please help... i would ask my mom but.. you know how awkward that would be..
