No, it can start at any time. You might have thought your period starts on the first of each month because periods are "monthly," but this just means that the average woman gets their period every 28 days. Once you get your first period, it will take about a year for it to regulate. Once it does, you will get a period around the same time each month, or you will have about the same number of days between each one.

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.
