Factors that break wudhu

Q: I was doing wudu, I stopped because I felt the need to break wind, so I did that and sometimes when standing, it can feel like it is between the thighs, so I squatted briefly to expel trapped wind. Started doing wudu again and somewhere in it, I felt a bubble, not sure what it was though and I don't think it came out of me, I think it was from my thighs and I don't think I heard or smelt anything, just had the feeling of a bubble escaping from my thighs. I just ignored it and prayed. I had doubts about it but it was maghrib so I convinced myself I was in wudu and prayed, but now I don't know.

Q: If a very small amount of blood or pus comes out (and was removed) from a wound or cut, will wudhu break?

Q: In wudhu if I touch my husband wudhu breaks? While performing umrah if I hold my husbands hand will my wudhu break? Please tell me.

Q: If someone started bleeding at zuhr time and had not prayed zuhr until 10 to 15 mins before asr and then they prayed zuhr. Then at start of asr they are still bleeding so they make wudu and pray asr. Now if they stop bleeding at asr time, will they have to repeat their zuhr or not? I heard there is a difference of opinion.

Q:

1. Someone told me that if only a drop of urine comes out you still have your wudu because a drop is less than a penny (coin), is this true?
2. All impurity which is less than 3 to 5 centimetres in diameter is excused. I am sure two drops of urine on your clothes will not make a circle which is more than 3 centimetres, is that true?

Q: When I hug and sleep with my wife sometimes a small discharge comes out (its not mani, just some fluid). Is ghusul mandatory on me to pray namaz / quran? Please explain me what needs to be done?

Q: I would like to know if someone sleeps for few minutes whilst sitting on a chair or car seat or aero plane seat, will his wudhu break?

Q: Does ablution break when you have confusion that ablution broke or not?

Q: Should a woman perform wuzu again and again for every namaaz after breastfeeding a baby?

Q: Fajr time I came out of washrum offered namaz then when I opened the book to recite surah yasin I felt some warm drops in my private parts. I thought that it was a waswasa and continued but after reciting I checked. There was very little moisture on my thighs and there were drops in my private parts which can be the result of water I used during istinja. I don't understand whether I was in wudhu or not?
