In Jain practice, there are some differences between Digambar and Shwetambar communities on how to handle Samvatsari and pratikraman when you are menstruating.

What you can generally consider:

• If you are menstruating and your tradition restricts certain rites on that occasion, you can perform pratikraman the following day when you are fully eligible, or you can do a pared-down form of pratikraman that focuses on atonement and forgiveness for the harm caused (parman) during the previous days.
• The essential aim of pratikraman—asking forgiveness from all living beings and resolving to refrain from harming—remains the same. Even if you postpone the full ritual, you should still engage in sincere reflection, repentance, and the intention to improve.
• If your local tradition has a standard rule (for example, postponing certain parts of Samvatsari or performing a shorter pratikraman during periods), follow that guidance from your guru or temple authorities.
• After your period ends, you can resume the full pratikraman, complete the missed portions, and renew your vows.

Key note:

• Because practices can vary, it’s best to check with your guru, tejopashri, or local Jain center for the exact expected sequence for your specific tradition (Digambar vs. Shwetambar) and community customs.

If you’d like, tell me which tradition you follow (Digambar or Shwetambar) and your location, and I can summarize the typical guidance given by that tradition and suggest a simple, respectful plan you can follow.
