Will she have to change her Niyah?Also i would like to know if you have women and old ppl wid u who u have to look after is it ok if u dnt walk fast while doing tawaf and between safa and marwa.
Praise be to Allah.
      If a woman enters ihram for ‘Umrah, then her period comes 
      and she does not become pure from it before ‘Arafah, then she should 
      intend to do Hajj, and thus it will become Qiraan, as happened to 
      ‘Aa’ishah (may Allah be pleased with her). She was doing Hajj Tamattu‘, 
      then her menses came after she entered ihram for ‘Umrah, and she was not 
      able to do ‘Umrah before Hajj. So she joined Hajj to ‘Umrah, and it became 
      Qiraan. 

    Narrated by al-Bukhaari (305) and Muslim (1211). 

    It says in Zaad al-Mustaqni‘: If a woman menstruates 
    and she is afraid that she will miss Hajj, she should enter ihram for Hajj, 
    and it becomes Qiraan. 

    Shaykh Ibn ‘Uthaymeen (may Allah have mercy on him) said: 
    What is meant by woman here is the woman who is doing Hajj tamattu‘, i.e., 
    she entered ihram for ‘Umrah so that she could then exit ihram, and perform 
    Hajj in the same year, and she reached Makkah on the fifth day of 
    Dhu’l-Hijjah and got her menses, and her period usually lasts six days, so 
    she will become pure (taahir) on the eleventh, i.e., after the standing [in 
    ‘Arafah] is over; hence she cannot do tawaaf and saa‘i and end her ‘Umrah. 

    We say to this woman: You have to enter ihram for Hajj, so 
    that you will be doing Qiraan, because the Prophet (blessings and peace of 
    Allah be upon him) instructed ‘Aa’ishah to do that when her menses came in 
    Sarif before she entered Makkah. The basic principle with regard to a 
    command or instruction [of a text] is that it implies something is 
    obligatory. 

    End quote from al-Sharh al-Mumti‘, 7/98 

    Sarif is a place near Makkah. 

    Thus it is clear that this woman will not be able to do Hajj 
    tamattu‘; rather she should change it from tamattu‘ to qiraan, and she has 
    to offer a hadiy just like one who does tamattu‘. 

    And Allah knows best.
