Ma'zoor

Ma'zoor sleeping through an entire salaah period

Q: 

1. If the wudhu of a mazoor person (urine incontinence) sometimes, but not always, lasts through a short salaah period, namely maghrib, will he still be considered a mazoor? 

2. If he accidently sleeps through a salaah period, he will not know whether or not something exited, since movement is little during sleep, it's unlikely something exited, will he still be considered a mazoor?

Repeating the salaah performed with a bleeding mouth

Q: Please assist in the scenario below: 

I went for a tooth extraction at 16H15 (Asr time sets in at 16H00 but I had not yet performed Asr). Just before Asr time ended I made Wudhu and prayed Asr with blood still coming out. The blood stopped during the time of Maghrib, so Maghrib Salah was no issue. 

My question is if I have to repeat Asr as I was not yet a Mazoor (as the bleeding was not found for a complete Salaah time) but I had to pray Asr with my mouth bleeding as time was running out.

Mazoor woman changing her liner for every salaah

Q: I consider myself a mazoor (excused person) due to chronic vaginal discharge. Nothing excessive but I have leaks especially during prayer. I wear panty liners to absorb the discharge. Sometimes theres a lot or just a few drops or even none (between prayer times). Example due to work I pray Zuhr at the end about 10 minutes before Asr. I still do a new wudu for Asr even though the time is very close. I do a new ablution for each prayer.

My question is, do I have to change the panty liner for each prayer? Or can I keep wearing the same one for 2 or 3 prayers?
