Yeap, thats right...it should be "In Process"...many CHC also maintain information within the "In Process" status that "Medical is received" once they receive medical from the DMPs..
but i never observed "Medical Recd" message for ND applicants...
As long your Ecas shows "In Proccess" you are safe. When you click on In Proccess it could be anything like 'We started proccessing your application from so on so date'
I can see from your profile that you attended interview, normal process is six weeks from the date of any event. You need to wait for another four weeks before you recv any meds. Don't you worry, you will be fine mate! All the Best!!
