All perfect praise be to Allah, the Lord of the worlds. I testify that there is none worthy of worship except Allah and that Muhammad, sallallahu ‘alayhi wa sallam, is His slave and Messenger.
You should know that the basic principle is that no Mathi or Wadi was discharged; hence, you are not required to check whether these discharges are vaginal or otherwise. Rather, it is sufficient for you to act upon the basic principle in this regard and consider this discharge to be vaginal. It is ritually pure, but it does invalidate ablution.
Moreover, if you suffer from incontinence of such vaginal discharge, you should perform ablution for each obligatory prayer after its time has become due and then perform the obligatory prayer and whatever voluntary prayers you wish until its time expires.
If you doubt whether this discharge is Mathi or vaginal discharge, you are given the choice to consider it as either of them and act upon the relevant ruling, according to the view adopted at Islamweb. Please, refer to fatwa 358021. We also advise you to disregard Waswaas (obsessive doubts), because letting yourself get carried away with them leads to grave evils.
Allah knows best.
