Sex / feeling fat and unattractive

pregnant
I am 26+3 today. My husband and i used to have sex once a week if not more. Now it feels like he is not attracted to me anymore as its once every two weeks if even and I need to initiate it. 
So I asked him yesterday and he told me that he wasn't as attracted to me anymore during pregnancy. I feel so fat and unattractive :(
Had to share!  
Any similar experiences ?
