I'll tell about our case. I ordered our GCMS on March 8th 2017 (it was actually the second time I ordered them). You get them like 30 days later, but the info is according to the date you ask them.
So, on March 8th 2017 our notes were stating that my eligibility as a sponsor was not started, that the eligibility of my wife (PA) was not started and I don't remember other details, but it was almost like nothing was started. Then on March 20th, we got SA and AIP. Then on March 21st we got DM. And we got these GCMS notes on April 8th or so.
So why do I tell you that story? Because you see that when they get everything they need (security checks were long for my wife), they process everything fast. March 8th notes showed nothing, and 13 days later we had DM.
So, don't stress with the process, it's just a matter of time.
