• Jainism does not teach that menstruation makes a person spiritually dirty in the way some other traditions describe. The core path is about non-violence (ahimsa), truth, and self-discipline, not ritual impurity tied to the menstrual cycle.

• In practice, there is variation between communities (Śvetāmbaras and Digambaras) and among households. Some Jain communities observe certain cautions or temporary restrictions for women during their menstrual period, but these are cultural norms rather than universal doctrinal rules. The nature and extent of any such restrictions can differ by region, family tradition, or sect.

• Importantly, Jainism does not center around goddess worship in the same way as many strands of Sanatan Dharma. Jain practice focuses on the Tirthankaras and the path of purifying the soul. There isn’t a doctrinal requirement to worship a goddess in every season or cycle, and the question of a goddess being “in her periods” does not arise in Jain sadhana.

• If you’re exploring a specific community (for example, a particular Śvetāmbara or Digambar tradition) or a temple’s custom, the exact practices can differ. It’s best to ask a local Jain authority or a knowledgeable elder from that community for the precise norm they follow.

If you’d like, I can share more about how Jain texts describe purity, temple participation, and what the common duties of Jain laypeople are, with references from traditional Jain sources.
