How to track your cycle when it’s irregular

Most period apps predict from an average. If your cycles run 35, 52 and 41 days, an average is useless. Track signals instead.

Three things worth logging

Cervical mucus, basal body temperature, and any spotting. Two months of this tells you more than a year of app predictions.

When to see a doctor

No period for 90+ days, very heavy bleeding, or severe pain are reasons to book in.
