You get your period once a month. And it can last 3 days or even 7. It depends on the person. I last 3 days and my mom, seven to eight. So there is no telling how long it will last. But you will definitely get it once a month unless you are pregnant.
Some periods can be as short as 3 days while others could be a week or two. I've heard of one instance where a girls period went for 26 days! However periods usually last on average about 5-7 days.
