Items disappearing from inventory

Yesterday I was playing on my survival world and everything was fine, I had 2 diamond pickaxes (one with silk touch and the other with fortune 2 and unbreak 3), also had a trident I were restoring for enchanting it later, but today when I start the game, I put an eye on my animal farms, my crops and my village for trading, but then I realize that I didn't had my diamond tools with me for no reason, checked everywhere but didn't find them.

Any solutions?
