IS coming on your period ever 18 days regular for a 13 year old n it lasts for 7 days
Hi! Yes it is, when you get older it will probably start to settle down a bit more! But when you 1st start out it can be VERY often and actually quite irregular! The aver is 28 days so there are women out there about every 35 days and every 21 days! It will balance out!
thank you hunn
