Why is my period late if I am not pregnant?

Answered by the AskDoc Medical Team · Medically reviewed under our Medical Director, MBBS

Cycles respond to life. Stress, sudden weight change, intense exercise, travel across time zones, illness, and poor sleep can each delay ovulation, which delays everything after it.

Recurring lateness has findable causes: PCOS, thyroid problems and high prolactin are the usual three, all diagnosable with simple blood tests.

One late period after a stressful month is rarely alarming. Three irregular cycles in a row, or a missed period beyond six weeks with negative tests, is the point to book a visit.
