Your very lucky not to have mood swings etc. Mine are very bad and I'm only 13! This might only be my family but when someone starts before they are a size 32B round the chest then they don't get any pain I unfortunately am a 34c :-( hope this helped! ... abs...x
I am 11 and I don't feel any different when having my period, except the fact I have to change pads and such. Is it normal? Will I get mood swings or cramps later in life?
It's possible that you will get the cramping and mood swings as you mature more due to the fluctuation of hormone levels before and after a mentrual period. Time will tell. Enjoy for now.
