Generally speaking, the days prior to, the days of your period, and the few days after your period are the least fertile times. However, this can vary, depending on the length and regularity of your menstrual cycle.
If your cycle is 28 days, meaning that you have a period about every 28 days, then your ovulation time (also the time when you are most fertile) would be about days 12-15. If you have a shorter cycle, then you would ovulate sooner. For example, if you have a period about every 21 days, then you would ovulate around days 7 to 10. Keeping track of your period on the calendar can help you figure this out.
Just keep in mind that many things can affect your cycles, making your period come earlier or later. Things like stress, illness, medications, or change in diet, exercise or sleep can affect you menstrual cycle.
