I died suffocated in a wall when I return of the Nether. 

I accidentally threw a ender pearl when I appeared on the portal and I suffocated in a wall.

I thing that when I respawn and go to the portal my items will be there.

But I don't find anything, I search on the nether my items but it weren't be there and on the World. 

Also, I respawn near the portal so I late like 15 seconds.
