no libido!!!

Help! I feel like Being pregnant has killed my sex life. I'm 9w6d and have no desire what so ever to be intimate with my husband since I found out I was pregnant at 4w. I keep trying to blame it on the fatigue, nausea, and sore boobs, that make me not want to be touched. Are any other lady's struggling with decreased libido? I don't want my relationship with my husband to suffer but I just have no desire or energy to have sex
