Yes, on a
veset day a woman is required to perform a
bedikah. You may attempt to time the
bedikah for when you seem to be staining a bit less.
After the fact, if a woman neglected to perform a
bedikah on her
veset, she has to perform a ‘make up’
bedikah only for the
onah beinonit.
Please note that there are different approaches to calculating
vesatot while using a hormonal contraceptive. For more information, please see our
article on the topic.
