I'm 13 and I've started my periods when I was 10.
But now at this age I'm getting my periods every two months at one point last year I got in every 4 months.
I haven't told my mum cause I'm scared of what she will tell me.:(
Should I be anxitious about what is happening? :confused:

Your period won't really regulate until about 18 or so. I think it is pretty normal.
