As others have said I would not put much credit into what the USCIS website is saying. I checked every 3 or 4 months for updates. So I filed in April 2022, got the NOA1 about a day after I filed. It said Nebraska Service Center but I found out it was transferred to the Potomac Service Center. In June of 2022 I checked our case status on USCIS and it said our case was being actively reviewed. Then there were absolutely no changes for months. At the beginning of this year I started to check more frequently. At the end of March it said 3 days estimated until a decision would be made. So a few days later I checked back and it had jumped up to another 3 months estimated wait. I was super disappointed. Then, about 3 days later I got the approval notice. So the extra time they tack on probably means nothing. Also you may not actually be at the NSC, you can find out if your case was transferred to a different service center.
Good luck! You've got a long wait ahead of you but it will pass and before you know it, you'll be ready for the NVC stage.
