Hi, Neha,
I got the PMP 2 months ago. I remember an option to save a PDF with my PMP exam summary, which is showing the score in each knowledge area and approval status. Did you see this window? I hope you got your PDF score, just in case. It appeared after the congratulations message.
Anyway, I received a PMI email with my certificate after almost 24 hours of exam competition, and PMP virtual badge after about 72 hours.
If you would like to follow up on your certificate status with PMI, you can call them on 0800 phone.
I hope this helps you.
