My turkey's missing its giblets!

I'm making my turkey stock tonight and went to pull the neck and giblets from my turkey. I was up to my elbow in the turkey, but no giblets to be found. Aside from being bummed that I won't be able to utilize the giblets, I'm worried that they're hiding somewhere deep within the turkey and I'll only find out when the sucker's roasting tomorrow.

Please reassure me that this has happened to someone else and I'm not giblet-excavating challenged.
