You are a Feb applicant first of all, can you elaborate more whats "in process" in your cic account? Are you checking your Client status thing or you are talking about CIC applicant personal account? Your review is in process or medical is in process?
If you are logging your cic personal account, there it shows if they have received your medical or not, and if you have passed your Medical or not, it states clearly there.
Being single or married, doesnt make any difference. If you are married there is a possibility of getting it delayed if there is any error in application or if they seek more information about the spouse or sometime it takes time to do the Background check... but 80 % of the cases, they process it under their given time. As far as your last question is concerned, I am a 21 Feb, 16 applicant and there are many who are in the same boat. We all are anxiously waiting for our PPR request, but we are hoping in next 2-3 months, we will be getting our request.
Hope it helps.
