I am still waiting as well. I have kept calling the uscis, really wish i heard something besides that it is processing and it is still within normal processing times. Day 166 and counting.
I am just happy i got a trip next month to be with her. Really was hoping she was on the return flight with me a couple months ago. I just want to see that noa2 and know I will be booking a flight for her soon.
We will get our noa2s and this waiting will soon be over though. Keep heads held high and stress as little as you can.
