has he cheated on me ?

I've just come home for my break in work and I was looking for another USB plug and in my bedside table drawer I found these (pic attached) female white trainer socks... There not mine and obviously not his I've never seen these before... We have a house and a dog and TTC I feel so so low right now I don't know what to do,;; he's in work all day with no phone signal till like 640pm so I can't even ask him yet.:: it's driving me crazy
