Late period on the pill?

Editorially reviewed on October 29, 2026. [TODO: medical reviewer]

Quick answer

A light or missing bleed during the break or inactive pills is common, especially on low-dose pills like Yaz. If you took every hormone pill on time, pregnancy is unlikely. If you missed pills, vomited, started an interacting medicine or missed two bleeds in a row, take a test.

Which type of pill?
Did you miss any hormone pills this pack?
Did you vomit within 2 hours of a pill, or have bad diarrhoea?
Did you take new medicines (for example rifampicin, some seizure medicines, St John's wort)?
Is this the second bleed in a row that did not come?

Educational only. Talk to a doctor or pharmacist if unsure.

How it works

The bleed on the pill is a withdrawal bleed caused by the hormone-free days, not a true period, so it can be light or absent. The NHS lists changes to bleeding as a common pill effect.[src] Filipinas on Reddit describe the same worry ("di pa rin ako dinadatnan") on the placebo week of Yaz.[src]

Next steps: when to test, missed pill helper, no period on the pill.

Frequently asked questions

Delay ng mens habang nag-pi-pills, buntis ba ako?

Hindi kadalasan. Normal ang mahina o walang withdrawal bleed sa pills. Kung may nakalimutan kang pill, mag-pregnancy test.

Should I start my next pack if I had no bleed?

Yes, if you took every hormone pill correctly, start on time. If you are worried, take a test; you can start the pack while you wait.
