ANSWER:

If you are 100% certain that you had passed wind, you must leave prayer and perform wudhu again as your prayer was invalid. 

But if you are doubtful and you did not hear a sound or found a smell, then this is whispering of satan and you must not act upon it.

Made my ablution,after that,passed a very little bit wind,in which i had no control,so i again made my ablution,then started salah in congregation behind imam,and then again i passed wind,a very little bit,no pressure,i didn’t know that i m gonna pass wind so that i can control,so,i fullfill my salah in that situation,is my salah valid?if not,what to do now?it was 2 days before and i was not sick
