Immediately following your final active pill cycle, you will observe
vesatot as you have been doing.
For the subsequent cycle, you will calculate
veset dates for the subsequent cycle based on the day on which your flow began. You will observe
veset hachodesh and
onah beinonit, but not a
haflagah, since the interval was wholly determined by conditions no longer present.
The next cycle (i.e., about two months after going off the pill), you will observe an interval day as well.
There is a range of opinions on how many
bedikot should be performed on each
onah and when. Some authorities require one
bedikah during the
onah; others require two or three. Some authorities maintain that a
bedikah right after the
onah is also sufficient. When there is a daytime
onah, and a woman customarily performs a
bedikah at the end of the
onah, it is preferable to perform it prior to sunset.
