Your periods aren't determined by the dates on the calendar, they are determined by your menstrual cycles and your cycles will never perfectly sync up with the calendar months. The average menstrual cycle is 28 days which is shorter than a month, cycles can change, and months aren't all the same lengths - there's no reason at all to think your period would always occur on the same day every month.

Menstrual cycles can vary in length due to fluctuations in hormone levels, stress, diet, exercise, or underlying health conditions. Changes in cycle length can cause periods to start earlier or later each month. If you are concerned about your menstrual cycle pattern, it's best to consult with a healthcare provider for a proper evaluation.
Not necessarily. The start date of your period can vary based on your individual cycle length, which is typically around 28 days but can vary from person to person. It is not always on the first day of the month. Tracking your menstrual cycle can help you predict when your period will arrive each month.
Girls have periods as a result of their reproductive system preparing for a potential pregnancy. Each month, the lining of the uterus thickens in anticipation of a fertilized egg. If pregnancy does not occur, this lining is shed through menstruation.
It starts between the ages of 10-16. Once you start it you will have it every month for about a week. It is okay if your body skips a month. Hope I helped!(: -13 yer old girl that started her period at 10.(:
Men do not have periods because they do not have a menstrual cycle, which is controlled by the fluctuation of hormones in the female body. Men do not have a uterus or shed the lining of the uterus like women do during menstruation.
Typically, girls who have not reached puberty have not started ovulating yet, which is necessary for pregnancy. However, in rare cases, precocious puberty can occur, which may lead to the possibility of pregnancy before the expected age.
