Ref. No. 41/976
In the name of Allah the most Gracious the most Merciful
The answer to your question is as follows:
In this situation, the woman should wait until she is pure. However, if the days of Hajj started and she is still on her menses, she should go through all rituals except Tawaf. She must delay the Tawaf till she gets pure. Nevertheless, if she is still in menses and the departure time has arrived then she should wear sanitary pads and perform Tawafe Ziyarat which is Fard. Doing Tawafe Ziyarat in the state of menses is a Jinayat, so she must also slaughter an animal, such as camel or cow etc. in the Haram premises. She should leave all other Tawafs. And there shall be no penalty upon her for leaving Tawaf.
And Allah knows best
