Counting veset from bedikah
2 September, 2009
I did a bedikah on a veset day (Tuesday) and found a bit of blood so I became a niddah. I did not have any actual flow of blood (no need for tampons or pads) until Thursday.
If it hadn't been for the veset I would not have had any reason to check. I could not get a clean Hefsek until day seven.
Do I use the Tuesday or the Thursday to calculate the date of next month's vesatot?
Vesatot are generally calculated from the onset of the flow, and not from the stain on the bedikah. Therefore, you should calculate next month's veset from the flow on Thursday.
If however, for three consecutive cycles you become niddah from a stain on your bedikah on your onah day, even if it precedes your actual flow, you would then start calculating your veset based on the bedikah and not the onset of the flow. If this does occur, you should make sure that you are actually becoming niddah from the stain on the bedikah. If it is not bright red, you can bring the bedikah cloth to a rabbi for evaluation, since not all shades of brown will render you niddah.
