In this state too she should wear the ihram from miqat, but she will not offer the two rakah salah and will not perform tawaf and sa’i after reaching Makkah. When the menstruation stops, she will perform her umrah after doing ghusl i.e. she will do tawaf of Ka’ba, then sa’i between Safa and Marwa. She can stay in Makkah in the state of menstruation; but she should not enter in Masjid-e-Haram.
