Hey love(ao),
It's normal for Ecas to still show in process for both the sponsor and the sponsored person. As you got the SA, the sponsor means that has been approved, but they rarely update the ECAS for that. I have been landed for almost 3 months now, and still on my ecas shows sponsorship application status in process. If your visa have already approved your medical examination, they will extend it for your. If they still didn't go through it they will probably ask you to take it again. Having received your AOR2 means that they received your application. Though it doesn't mean that they started processing it yet. If you want to see what's going on with your application you can order your GCMS http://www.cic.gc.ca/english/department/atip/requests-atip.asp
I know it's a very painful and stressful process, but you can only be patient and positive that it will be over soon.

Best of luck
