In the Name of Allah, Most Gracious, Most Merciful.
All praise and thanks are due to Allah, and peace and blessings be upon His Messenger.
In this fatwa:
Answering your question, the Fatwa Center at Islam Q and A, states:
In that case, the woman should do wudu after the time for each prayer begins, then she may offer whatever she wishes of obligatory and supererogatory prayers with that wudu, and emission of those secretions will not matter.
Some of the scholars are of the view that these ongoing secretions do not invalidate wudu.
To be on the safe side, one should do wudu, but if that is too difficult, then there is nothing wrong with not doing it, because the view that the secretions do not invalidate wudu is a strong view.
Based on that, on your wedding day you can do wudu before or after the Adhan of Maghrib, and keep your wudu until you pray Ishaa at the appropriate time.
If it is too difficult for one who suffers from incontinence – whether in terms of urine, gas or secretions – to do wudu at the time of each prayer, it is permissible for him to join Zhuhr and Asr, and Maghrib and Isha, offering two prayers together with one wudu.
Almighty Allah knows best.
