Change in veset on pill

28 June, 2013


Hi I have a question about calculating a veset. For years I've been on the pill (taking 3 packs at a time) and always got my period 4 days after stopping – a 67 day interval. I recently got my period only 3 days after stopping. What vesatot do I keep now? Do I need to keep the day of the month?


Since you have established a set pattern of bleeding four days after you stop taking the pill, you have established a veset haguf kavua, and are no longer required to observe the usual vesatot of yom hachodesh, yom haflagah, and onah beinonit. Even if you stray from your set pattern (as you did this time), you are still exempt from the three usual vesatot, since halacha recognizes that your periods are controlled by the action of stopping the active pills.

Therefore, the next time you stop taking the pill, you are required to observe an extended veset including both the 3rd day (based on this last period) and the 4th day (your usual veset) after your last active pill.

Please see our section on Vesatot and Hormonal Contraception for more details, and feel free to get back to us with any further questions.
