Firstly: 

It is permissible for a person who is in a state of minor impurity to read Qur’aan without touching the Mus-haf, and it is permissible for him to touch books of Tafseer or to read Qur’aan from them. But he is not allowed to touch the Mus-haf unless he has wudoo’. See the answer to question no. 10672. 

Secondly: 

Vaginal discharge is taahir (pure), but 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 if it is continuous, then it comes under the same ruling as urinary incontinence, so the woman should do wudoo’ for every prayer and then offer whatever obligatory and naafil prayers she wants, and touch the Mus-haf, and it will not matter if this discharge comes out. 

But if the discharge is not continuous, then you can read from the Mus-haf by putting a barrier over your hand between you and the Mus-haf, such as gloves and the like. 

See the answer to question no. 2564. 

And Allaah knows best.
