Her body is simply not ready yet.

The average age of menarche is 13 but anything up to 18 years old is totally normal, if you haven't gotten your period by the age of 16 you may want to mention this to your doctor but as long as you are going through puberty there is likely nothing wrong.

Well in some occasions its not the period but the tearing that is causing the bleeding...

So if you dont get it after 16, that means you are preagnant or you have a problem. And no sex doesn't cause early periods!!! :)

When are you going to start your period?

The start of puberty is when your breasts start to grow and you begin to grow pubic hair! Every girl has their period at different ages some as early as 8 and some as late as 19! About a year and a half before your period you would notice some thick white mucous discharge coming from your vagina! When it happens it happens be glad not to have it yet!
