Would a woman be considered sinful for intentionally abandoning prayer if she delayed a prayer slightly past its time, and then menstruation or the pre-menstrual spotting occurred?

The time for prayer is extended, and a Muslim does not sin by delaying the prayer within its time, unless they know or strongly believe that an impediment will occur preventing them from completing it, such as menstruation or death. In such cases, it is obligatory for them to hasten the prayer before the impediment occurs. However, whoever doubts the occurrence of an impediment is not obligated to hasten.
