I made my first bitcoin purchase using Coinmama.  The Coinmama site shows my transaction as complete but the transaction is not showing up in my wallet.  I am afraid I did something wrong and hope I didn't just lose all my money!  Any help would be greatly appreciated.  Thank you!

FYI
I cut and pasted my "receiving address" from my electrum wallet onto the Coinmama site and then confirmed that address before completing the transaction.  I saved the request in my wallet and have waited about 30 minutes.  My wallet balance is still showing zero and the saved request is still showing pending.  The order on my Coinmama account is showing completed.
