Hi Irisadz, yes, do not worry. As you can see from my timeline my Visa office started processing a little over a month since the sponsorship stage was approved. Then it took a few days for the e-cas status to change.
I read somewhere that CIC actually hire some company to take care of the status online, they don't actually action it themselves.
Also, to give you some more peace of mind check out trackkit.com. There you can find timelines for many applicants for all over
