What do I do if my iCloud backup didn't finish as I though it would overnight and now I've updated my phone? Now I don't have the option to restore any backups....

I set up my iPhone to back up to the cloud, it should have backed up overnight while it was plugged in and charging. My bad, I did not check to make sure that it did, as it was the very first time I ever backed up my data to the cloud. I just went and updated my iPhone to iOS7 and went to restore my storage from the cloud, and I saw that it never completed backing up. How can I get my storage back from the cloud now? I see some things still on my phone but not all....

Many thanks in advance!!
