Factors that break wudhu

Q: If after making wudhu and drying hands, one hits a wall and thereby a little piece of thin layer skin peels off, does this break the wudhu?

Q: I have had a vaginal discharge that is whitish yellowish/cream in colour. This discharge has been for years. After the birth of my child it is still there. It is very uncomfortable since my underwear gets stained and I just feel napaak. The gynaecologist says that it is normal... But I don't know whether I am paak or not. I have been changing before each namaaz or when I feel the discharge and the salah time set. This is very difficult especially when going out. I will be going for umrah inshallah. PLEASE advise me what I should do since to make whudhu and change at every salaah is very difficult in the haram. PLEASE advise.

Q: Sometimes, in my drips, I notice blood coming out from me into the tube, does this break wudhu? Also when my drip gets opened to put a new one, some droplets of blood pour out, does this break wudhu?

Q: Does inserting suppositories break wudhu?

Q: I had a cut on my knee and it bleeds, then I put a plaster on it. When I make wudhu then do I need to make a new wudhu for all namaaz?

Q: I was performing salaah and during my last sajdah I felt accumulated wind about to come out i.e. I had the urge to break wind, when I sat back from sajdah that feeling was gone. Now I don't know whether the accumulated wind came out without me noticing it, or that the accumulated wind just disappeared into my body. In such case is my wudhu nullified? Can the feeling of accumulated wind just disappear (without coming out) back into the body? Or must I regard it as having come out even if I did not feel something coming out? Should I repeat the prayer and the prayer I have prayed after it?

Q: If I make wudhu and whilst I am making wudhu I break wind, do I have to start with the wudhu again, though I never had wudhu because I never completed the wudhu?
