Adjustment of Status - I-485

Hey guys! I am currently filing an AOS application.I am currently in the US on a F1 visa. Me and my husband filed my AOS paperwork end of December (12/30). The application package included I-130, I-485 & I-765. The package got delivered on the 30th Of Dec. I have still not received any NOAs. We have not received email, text or even the hard copy NOA. I have been going over the timelines on websites and it looks like mine is taking excruciatingly long :( . I am getting very worried at this point. Its been 3 weeks and I haven't heard anything back from the USCIS. At first I assumed the delay was because of the holidays but now that its been 3 weeks and not a peep from USCIS, I am really starting to worry. Is anybody else on a similar timeline or in a similar situation? It would be very helpful to know that I am not alone in this. Oh, also I got a notification saying that my checks were cashed a week ago, so I thought there was a ray of hope there for a bit but its been 1 week exactly since they cashed the checks and I still haven't even received an initial NOA, forget the snail mail one. Here is my timeline.
 
AOS timeline:
12/29/2015: Application sent to Chicago Lockbox
12/30/2015: Application delivered at Chicago Lockbox
01/14/2016: Checks cashed
 
Please advise! I am really worried at this point.
