Hi there!
It's definitely way too early for the medical exam. These tend to happen at the end of the process, closer to when you actually get the PR.
From what you've told us, I think it's quite unlikely you'll get the PR by Nov 1. March 2nd to Nov 1st is under 8 months and currently the average processing time is 12. If you're from the US, that might help and lower your processing time. On the other hand, you're applying common law which is more difficult to prove and can sometimes drag on a bit because they ask for additional proof and/or interviews.
The PR card thing is for the literal physical cards - it means it'll take around 45 days to get the card after you've completed the landing process (which happens after your PR application has been approved).
Basically, it could happen, but it's unlikely. The majority of apps fall into the 11-13 months range, if looking at the different spreadsheets here, as well as the official site giving a 12 month average.
As for being contacted, now that I've gotten my OWP, I don't expect any correspondence for pretty much months to come, just to give you an idea.
Hang in there!
