At the moment, a lot of October and September applicants are still waiting for their Passport Request. And you haven't even performed your medical exam as well as submitted your PCC, so it is kinda farfetch to estimate how long you will get your Passport Request after your medical exams. Different Panel Physicians have different availability, and varying time in uploading the medical results. Some doctors could take few days, others could take few weeks. Then, we don't know if your medical exams will go smoothly and won't need another test.
Different Visa Officers may take varying time in processing your files afterwards. They could also take few days or few months. Few chances that they will need to re-review your file again. So there is a lot of factors here, and it would be hard to estimate when you will get your Passport Request. Good luck with your case thou~
