Chapter 01Health & Wellness

Why is my period late?

Stress, weight change, hard training, travel, birth-control changes, and — of course — pregnancy are the usual causes. If cycles are irregular for 3+ months, check with a doctor about thyroid or PCOS.

Follow-up questions

How late is too late?

More than a week past expected date warrants a pregnancy test if you're sexually active.

Does stress really delay it?

Yes — high cortisol suppresses the hormones that trigger ovulation.
