Mishkat al-Masabih 2572
‘A’isha said:
We went out with the Prophet mentioning nothing but the hajj , and when we were at Sarif (A place near at-Tan'im) I began to menstruate. The Prophet came in and finding me weeping, he said, “Perhaps you are menstruating.” When I replied that I was, he said, “That is something which God has decreed for the daughters of Adam; but do what the pilgrims do, with the exception of going round the House, till you are purified.” 

Bukhari and Muslim.
وَعَنْ عَائِشَةَ قَالَتْ: خَرَجْنَا مَعَ النَّبِيِّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ لَا نَذْكُرُ إِلَّا الْحَجَّ فَلَمَّا كُنَّا بِسَرِفَ طَمِثْتُ فَدَخَلَ النَّبِيُّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ وَأَنَا أَبْكِي فَقَالَ: «لَعَلَّكِ نَفِسْتِ؟» قُلْتُ: نَعَمْ قَالَ: «فَإِنَّ ذَلِكِ شَيْءٌ كَتَبَهُ اللَّهُ عَلَى بَنَاتِ آدَمَ فَافْعَلِي مَا يَفْعَلُ الْحَاجُّ غَيْرَ أَنْ لَا تَطُوفِي بِالْبَيْتِ حَتَّى تَطْهُرِي»
