Love the game but just one problem..

I had a 10 km egg that should have hatched today.... well when I was walking I looked through all my Pokémon and I checked my eggs and the one that was supposed to hatch wasnt there, I have no new Pokémon at all. So I hope it was a glitch and doesnt happen again cuz a little irritated with it. Please fix it if it has happened to other people too!!
