Your ITA Letter should have stated which stream you were applying under - FSW or CEC. You should log back in to your myCIC account and re-read it; It's rather important to know which stream you're in, because there are different criteria to satisfy each stream (for example, FSW has to have 1-year of continuous full-time employment in one NOC Code, whereas CEC's 1-year of work experience can derive from multiple jobs with multiple NOC Codes, as long as they're all Skill Type/Level 0, A, or B; for another, FSW has to provide proof of settlement funds, while CEC doesn't).
Based on your statuses, it looks like you're in IP2 (IP2's BGC status usually reads "We are processing your background check..." while IP1'S BGS status usually reads "Your application is in progress...", although it's a bit odd to be in IP2 and have your documents still under review. But you can't rely entirely on the myCIC statuses. As legalfalcon, the resident attorney on this forum often explains, using the statuses to determine at which stage your application is, is pure assumption and conjecture.
For this reason, you can't and shouldn't have any expectations based on the myCIC account statuses. Even if we could rely on the statuses, there are too many things that could happen in 'IP2' to make an accurate guess as to how much longer your file could take. You could get PPR tomorrow, or you could get it a week from now, or you could get it a month from now (depending on how many applications are ahead of yours and how many human resources are available to process the applications, at whichever Centre or Visa Office your file is being processed), or your file could be "put down" by some Immigration Officer and "left to gather dust" for months more (as some unfortunate persons have reported after reviewing their GCMS notes), or you could get selected for additional security screening and have your application processing extended by a further 4 - 12 months.
There's no use speculating. I know the wait is hard, but just breathe and try to find other things to occupy your thoughts and time until one day you get the Golden Email (but check your email and your myCIC account once a day, just in case, as the deliver of the PPR notices is varied and flawed - emails going to spam, people getting the message in their myCIC account but no email to notify them about it, etc.)
