questions about salaah

suddenly i have bad thinking in my mind during wadhu and prayer and oher times. wen it comes my mind, i avoid it or try to forget it. but i fear madhy or mhony may be comes out. if mhony comes out, then i have to take shower, otherwise i cannot pray. so i am afraid during wadhu and prayer time. one day i doubt mhony comes out though because i feel little exicited and same time try to avoid. then i take shower and pray magrib but the prayer is late. so i am scared and may be did not give salam at the end of salat. every time i checked and find milky, sticky vaginal discharge. how can i get rid from this feelings.
