How do you know when your period is coming?
There may be signs. There may not be. For some girls, the signs that their periods are going to start are: tender breasts, feeling tense, and swelling of the abdomen or other parts of the body. Sometimes there’s a crampy feeling in the back, legs, or abdomen. Some girls get pimples a few days before.
Some people mark a calendar with an X on the days they bleed. Keeping a calendar for a few months may let you see a pattern. If your pattern is regular, tracking your period on a calendar will let you be able to predict when your next period may arrive.
As you get older, you’ll become more familiar with signs that your period is coming. Learn more about your period.
