Finally able to join this AOS thread

Self-prepared my application:
I-130
I-130A
I-485
I-485 Supplement A (I am a 245(i) grandfathered derivative)
I-864
I-765
I-693 (medical exam)
G-1145 (eNotifications)

This is my timeline so far:
Sent 2/21/2020 (via FedEx 2 day)
Delivered 2/24/2020

Now I'm worried because there's been radio silence from USCIS since they got my application a week ago; no G-1145 notifications, no myUSCIS updates, no receipt notices, they haven't even cashed my checks. Is this normal??

I was hauling ass to send my application in before 2/24 to avoid the new public charge rule. I'm thinking maybe because they received it on 2/24 as they were changing the process, that's causing a delay. I dunno, maybe I'm speculating too much. This is what happens when entering the dreaded waiting game with USCIS.
