Experiencing touch aversion

I’m in my first trimester and feeling really fatigue. And probably because of fatigue, I lost interest in doing a lot of things and really don’t like to be touched. Even seatbelt that touches my skin irritates me and unfortunately for now I don’t like to be touched by my husband. This upset my husband a lot and he thinks I’m avoiding him .. tried to explain to him but he doesn’t seem to accept the explanation :(
