No news means good news kash.
In my view as your docs had reached CIC almost more than 2.5 mnths ago,which is a pretty long time for REJECTING the case, as if the IO is not convinced abt your AEO ,he will not definitely linger on your case for such a long period.As far as I know BG checks are done only if the person has scored minimum qualifying score(67) .
So just be relax n wait.I hope u ll soon receive a good news ,CHC must be busy with ur BG checks and as soon as they are over u ll receive a PPR.
Regards
P.S. Plz read my post mentioned at the link pasted, may be u ll be get a better idea abt your case:
