Had relations on onah
16 July, 2009
My onat haflagah usually falls out at around 29-31 days. This month i made a mistake and had intercourse on day 27, only to realize afterwards that that was an onah day (I had a shorter cycle two months earlier). I am absolutely terrified that I might have gotten pregnant. Can you give me some halachic information about this situation?
Even if you did get pregnant from intercourse on an onat prishah, there are no halachic ramifications. While relations are forbidden on the onah, you are not actually a niddah until the bleeding begins, so the child would not have been conceived as a result of relations during niddah.
Furthermore, it is unlikely that you got pregnant on the 27th day of your cycle. A woman can get pregnant only around the time she ovulates, which is generally 10- 14 days before the next period. Since you are nearing the end of your cycle, it is most likely that you ovulated a while ago and cannot get pregnant at this point.
You should make efforts that this does not happen again – either mark your calendar and leave it in a conspicuous place for you and your husband to see, or even program a reminder on your cell phone if necessary.
