As someone who almost lost her mind during our excruciating wait for PGN, all I can tell you is what I wrote above.
We each have our own timeline - some are quick, some are within normal timeframes, some are cruelly slow - no reason. Just the way it is.
I remember our facilitator saying (the day of our embassy appt.) "when it comes to the PGN, we all just wait. We know when they let us know."
Be well and try not to fuss,
