Answer
(Fatwa: 1827/1555=B/1429)
If she does not find so much time in which she can perform salah in a state of purity, then she is mazoor (excused), she should make fresh wudhu in every salah time and perform obligatory salah of the time and as much nafl as she wants. Her salah will be valid even if the yellowish white discharge continues while offering salah. You should get her treated before going to Hajj so that she may do tawaf easily while being pure.
