I found the waiting after we had sent the application off the most difficult time so I understand what you are going through.
As I see it, there are a few different possible scenarios here.
1- You have provided everything required and the visa is granted.
2- Your application is missing some evidence and you are contacted by UKVI. You provide what they are asking for and the visa is granted.
3- Your application is missing some evidence and your visa is refused. (They are under no obligation to contact you).
Even worst case, with example 3, they will furnish you with a letter explaining the grounds for refusal. You address the point(s) mentioned, you reapply and the visa is granted.
I'm keeping my fingers crossed for 1 or 2 for you though!
