However, if the reason you don’t have periods is down to contraception, such as the pill, this might make it particularly difficult to track your periods. “The very role of contraception is to alter your hormones,” Welsh says, explaining that your menstrual cycle will be altered by this and therefore might not be consistent.

There are some things you can keep track of when it comes to monitoring your cycle, even if you don’t have periods, though. For example, you can make a note of:

whether you have had sex (protected or unprotected)
any tests you’ve done (such as ovulation tests)
any contraception you’ve used
other events you feel may have impacted your period or fertility.

You can make a note of these things either using a pen and paper or by using a period tracking app. Most people track their period on an ongoing basis. However, you might be able to notice patterns after the first few months of doing so.
