Really hoping for my BFP

Emma • Hi im Emma, im 29 years old! I have 2 children one 6 one 4 and trying for a much wanted 3rd baby to complete the gang!
So AF is due in 3 days. 
Iv had quite abit of creamy lotion like discharge & my cervix seems to be medium height & quite soft to touch. Anyone had this before a BFP?
