Changes in the timing of periods is pretty common. If you have a period then you aren't pregnant. What happens during the time before you have a period is that the lining of your uterus (the endometrium) builds up, getting ready to support a developing pregnancy. If you don’t get pregnant, this lining isn’t needed, and your body will shed it through your vagina as your period.
