You really need to chill, brother. What's going to happen by panicking/worrying/asking again and again when PPR will come or status will change?
Nothing will happen. It's not in your control. If you get upset and start the comparison game, then you will get sick with worry when someone posts here that their background check has started/has completed. You are not them and they are not you; apples and oranges. Different circumstances.
The lack of control and clarity over a situation is what breaks most people. When you had the application, you could add, subtract, edit, restart etc.So you had a sense of control of when to submit it, if you wanted to pay the R.PR. fee upfront or not and so forth. Now, after submission, NOTHING is in your control. The messages that you see on the application portal may not be updated/refreshed; in fact your BCG check may actually be ongoing at the moment and you may not be aware.
For your own sanity and good health, I would ask you to chill out and recommend reading some Stoic literature, and drowning yourself in hobbies and your 9-to-5 job. What is beyond your control, don't worry about; you did the best you could under the current circumstances.
Have faith in the Universe. If it happens it happens, else always find a Plan B.
