In the name of Allah the most Gracious the most merciful
The answer to your question is as follows:
If the departure time has arrived and the woman is going thforugh menses and she is yet to perform Tawaf-e Ziyarat. In this case, the woman should wear sanitary pads and perform Tawafe Ziyarat. 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 as a penalty.
And Allah khnows best
