She gets a sticky white discharge before her period and a week afterwards
Question

                One or two days before my period comes, I get a sticky white discharge, and again a week after the period ends. What is the ruling on praying and fasting on these days? Do I have to repeat wudoo’ for minor impurity only or for major impurity?.
Praise be to Allah.Firstly: 
This sticky white substance 
    comes under the same ruling as other secretions, and is subject to further 
    discussion. 
If it is continuous, then 
    it comes under the same ruling as urinary incontinence, so you have to do 
    wudoo’ for each prayer after the time for it begins, and these discharges 
    will not matter after that, even if that happens during prayer. 
If it is not continuous, 
    then there is a difference of opinion as to whether it invalidates wudoo’. 
    The majority of scholars are of the view that it does invalidate wudoo’, but 
    some of the scholars are of the view that it does not invalidate it, because 
    there is no evidence to that effect. But to be on the safe side, one should 
    follow the view of the majority. 
Secondly: 
This discharge is taahir 
    (pure) according to the most correct view, so there is no need to wash them 
    off one’s clothes. This is the view of Abu Haneefah and Ahmad, and it is one 
    of the two views narrated from al-Shaafa’i, and was regarded as correct by 
    al-Nawawi. 
This view was also favoured 
    by Shaykh Ibn ‘Uthaymeen. (May Allaah have mercy on them all.) 
He said in al-Sharh 
    al-Mumti’ (1/329): If these discharges come from the vagina, then they 
    are taahir (pure), because they are not waste products of food or drink, so 
    they are not urine. The basic principle is there is no najaasah (impurity) 
    unless evidence is established to that effect. And if a man has intercourse 
    with his wife, he does not have to wash his penis or his garment if anything 
    gets onto them; if it were naajis (impure) then that would imply that maniy 
    (semen) would become naajis, as he result of being contaminated with it. End 
    quote.  
See also al-Majmoo’ 
    (1/406); al-Mughni (2/88). 
Thirdly: 
These discharges do not 
    affect the fast. 
To sum up: you may fast and 
    pray, and you should do wudoo’ when these discharges come, unless they are 
    continuous and last all day, in which case you should do wudoo’ for each 
    obligatory prayer when the time for it begins, and you can pray with this 
    wudoo’ whatever naafil prayers you wish, until the time for the prayer for 
    which you did wudoo’ ends. 
And Allaah knows best.
