It is a prejudice among smarta-brahmanas that a widow must observe fasting on Ekadasi but a woman who is sa-dhava - who has her husband - should not. It appears that before Lord Caitanya’s request, Sacimata, being sa-dhava, was not observing Ekadasi

It is a prejudice among smārta-brāhmaṇas that a widow must observe fasting on Ekādaśī but a woman who is sa-dhava—who has her husband—should not. It appears that before Lord Caitanya’s request, Śacīmātā, being sa-dhava, was not observing Ekādaśī. Śrī Caitanya Mahāprabhu, however, introduced the system that a woman, even if not a widow, must observe the Ekādaśī day and must not touch any kind of grains, even those offered to the Deity of Viṣṇu.

CC Adi 15.10, Translation and Purport

Mother Śacī said, “You have spoken very nicely. I shall not eat grains on Ekādaśī.” From that day, she began to observe fasting on Ekādaśī.
