Does this sound normal? Puberty.?

1. I got my period at 11 but it didn't come again until I was 13. (I am 13 now). It has been regular for awhile but if I get stressed instead of missing a period it comes right then when I am stressed.

2. My friends have had underarm hair since they were 10 yet don't have their periods yet I have my period and have no underarm hair. Is that unusual (for me?).

I think thats farely normal because your first year or so is usually pretty messed up
But at the time you coudve been under or overweight because that effects it too
Stress thing is also normal i get that but not all the time its weird sometimes im stressed and it will come for like the 2nd time that month and others ill be stressed and nothing for like 2 months

Consider yourself lucky about the armpit hair its just another place to shave lol
Also i have a half similair thing as i get hair only under one arm
:S

I am not a woman, and therefore do not have periods, but I do think that if you're worried about it, and can, you should try to see a physician, since it could be something alot worse. You could end up with an reocurring infection, or maybe something worse. goodluck, I really hope it's nothing.

Everything about U, that U think is not normal because others are a little different..is NORMAL.

i would says its normal cause everyone is different
