I-129 processing time

I got selected in 1st lottery and my Petition was filed on 27-jun-2021 (form I-129 , California).
However still status is “My Case Was Received”.
Can anyone advise how long it will take to change the status.

Why didn’t you opt for premium processing?

It is just odd not to process for so long. Ideally it would have been processed with a start date of 1st October 2021.
