At what age, a girl's period starts?

[letuswaltzforthedead]

Depends on the girl, but women usually get it at 12 (used to be 16 a few decades). I wasn't even 10 when i first got it lol.

How can it be16 when it can be 10?

10 and 16 are great different ages.

[letuswaltzforthedead]

Not every woman has hers at the same age. 16 was the average age a while ago (not sure how long ago) and now the average age is 12.4 I think.

But age difference is so great. Look at a 10 year old. And look at a 16 year old.

[Vivaldi]

I mean 16 is nothing like 10.

[letuswaltzforthedead]

True, there's plenty of reasons why the average age of menarche is getting younger like increasing inclination to fast life history strategy (which means like what it sounds) or worse environments growing up. Again, the average is 12 currently, I just had it younger than that but not young enough for it to be considered an early puberty.

Age 12 or somewhere around there, within a year or two. I've had to teach some 11 or 12 year old girls and their attitude changes are crazy.

My cousins were bleeding at 12 when I had to baby sit them... take and watch at pool... etc. Pool and swim team is how I know...

Depends on the girl. I had my first period at 13.5 years old

[whereismyjohnny]

Most girls get their first period between 10 and 15. Some get it a bit earlier than that, some later.
