Is it necessary to repeat the ghusl if the white discharge (al-qassah al-baida') reappears after the initial ghusl?

If a woman sees purity by one of its two signs, she must perform ghusl (ritual bath), and any subsequent white discharge does not harm her; because it is not considered menstruation. Therefore, if she has verified purity and performed ghusl, she is not required to perform ghusl again because of these discharges.
