Hi Shilpi,
You should see your certificates if you login to the link below:
https://www.microsoft.com/en-us/learning/dashboard.aspx
This is your dashboard, you should have three sections on the page: Badges, Certificates & Transcript.

Click on Certificates to see all your earned certificates, you will be automatically redirected to a page where all your certificates will be shown and there you will be able to preview or download your certificates.

Best regards,
Leon
