Sad dog while pregnant?

I am 10wks 2 days pregnant! I have had pretty bad all day morning sickness for the past 4 weeks that I usually am asleep and sick in bed most days! I feel like my dog is sad and started to act out today by chewing on the wall. I do not play with him as much because he is very rough when we play and I am scared he will hit my stomach or make me fall. My husband does play with our dog but he works long hours and does not have the energy to pay attention to him and me while I am sick. I try my best to keep him entertained with treats and toys. Is anyone else experiencing this with their dog ? Please not hate comments.
