Vaginal Discharge

As Salaamu Alaikum,
This is a very touchy fatwa. I’m trying to understand why vaginal discharge that occurs regularly invalidates wudu. On Islâmqa.info the evidence they gave as to why regular vaginal discharge invalidates wudu is the Hadith about istihadah. May I ask how this Hadith serves as evidence? Vaginal discharge isn’t blood which is why I want to understand how this Hadith serves as sufficient evidence that vaginal discharge breaks wudu. A separate scholar, said that vaginal discharge doesn’t break wudu because there isn’t any evidence to suggest this. I need proper clarification because I am in a dilemma. The day before I am writing this question to you I was suffering from a greater amount of vaginal discharge than I was used to. Because of this I inserted some tissue on what I think is the outer part of my private area because I have read on a separate fatwa that you can insert tissue to stop the flow of discharge so your wudu won’t break. My problem arose when I realized that the fatwa said “insert”, my hymen is still intact so that is why I’m wondering if I really inserted the tissue far enough to where if any discharge flowed out my wudu would still be intact. What is your opinion on this. The tissue was definently inserted somewhere because it didn’t come out unless I took it out so I’m not sure what to think. I prayed form asr to Zuhr the next day like this. And I’ve done this for many salahs in the past. If I pulled out the tissue and saw discharge does that mean my salah was invalid and I must redo each of these salah? Also what is the ruling on waiting to have a fatwa answered before I was to for example wait to reoffer each of these salah if they were invalidated?
