Is the Halacha different regarding Onos that are within a couple of months post birth?


Must they all be kept?

Is the difference only regarding Veses Kavua.

How does it work?



After a birth one must keep the Onos (Hachodesh, Beinoni, Hafloga) only after she started having her period again (which usually will not happening for a couple of months after a birth).

Those Onos are to be kept as an “unfixed cycle”.

One cannot set up a fixed cycle during 24 months after a birth, even if 3 periods happen at the same date and Onah.
