No idea when to expect period

24 December, 2015


Last month I went off my birth control for the first time since I got married. I was expecting my period a few days ago so I have been avoiding intercourse as I dont want to accidentally do anything forbidden during my ona of prisha – is there any logic to this? Is it ok to have intercourse if I really have no idea when my period will come (or if it will at all – trying not to get my hopes too high yet though – but will take a test within the next few days if it still doesn't show). I never kept track of my period before I was on the pill so maybe I just have longer intervals between cycles. Is there any reason to be avoiding intercourse?


It is common for cycles to be irregular in the months after going off a hormonal contraceptive.

The veset days are designed for women who are not certain when they will next become niddah.  If you have passed the day of the month, thirtieth day, and interval from your last becoming niddah, then there is no further requirement for you to separate from your husband.  For more information, please see our site's articles on vesatot
