Bitcoin transactions are confirmed on the bitcoin blockchain. They are usually confirmed at a rate of 1 every 10 minutes with first confirmation usually after 5 minutes. May take around 30 minutes to get the 6 confirmations.
You can track your transaction on a block chain explorer if you can find the transaction ID on 5D.
Here's a link to an explorer

Copy and paste the transaction ID into the search box near top and press enter, it will give you an update about how the transaction is progressing. You can refresh the page for updates.
Hope this helps.
PS Its a pretty cool way to transfer funds without using a bank.
