Sayyidah Aisha Siddiqa (may Allah be pleased with her) narrates: I came to Makkah while I was menstruating. I did not perform the Tawaf of the House (Ka'bah) nor the Sa'i between Safa and Marwah. I complained about this to the Prophet Muhammad (peace be upon him), so the Prophet (peace be upon him) said: Do all the acts that a pilgrim does, except do not perform the Tawaf of the House until you become pure.
