Can sex make your period come early?

Well in some occasions its not the period but the tearing that is causing the bleeding... And its normal to start you're period early, some girls get it when they are 7-8 years old and the latest would be when a girl is 14-16... 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!!! :)
