Period tracking tutorial

Let's talk a little bit about what being "regular" means. Once your period is fully up and running on schedule, it will usually and predictably occur every 4 weeks or so. However, some women will have periods more frequently (like every 3 weeks) and others less frequently (like every 5 weeks). The number of days you bleed will also vary but is usually anywhere from 3 to 7 days. Everyone is different.

It's tempting to think your period comes at the start, middle or end of every month, but sooner or later the calendar will mislead you (as you know, not all months have the same number of days!). What's better to do is mark your period on a calendar (either on paper or in your phone). Here's an example of what a 5-day period with a 33-day cycle might look like:

 Count out 33 days from the first day of your last period (here, January 3) and you can expect your next period to start on February 5.

Here's another example of what a 6-day period with a 27-day cycle might look like:

Count out 27 days from the first day of your last period (here, January 28) and you can expect your next period to start on February 24.

Neither of these examples follows a calendar exactly but they are still considered to be "regular."
