The Sunnah and scholarly consensus indicate that menstruation does not prevent one from entering Ihram, so a woman may enter Ihram even if she is menstruating, but then she should not do `Umrah until she becomes pure and does Ghusl.

It is permissible for a woman to enter Ihram with bangles or rings of gold on her hands. However, it is prescribed for her to conceal that from non-Mahram men, to avoid temptation.

-If a menstruating woman reaches the Miqat and intends to do Hajj, then she should enter Ihram from the Miqat, then when she reaches Makkah she should do all the actions of Hajj except for Tawaf and Sa`i, which she should delay until she becomes pure. -If her period comes after Tawaf, then she may do Sa`i even if she is menstruating.
