Lack of sex? 😒😩 s/o issues...

My boyfriend and I have always has a very wonderful and frequent sex life.... Until I got pregnant.  The more I show the less he will have sex with me (I want it ALWAYS).  Now days we mostly have sex first thing in the morning where it doesn't take much work.... I usually don't even reach my ending point but I only do it cause I know it's my only chance to get some. He used to always make sure I was done before we were done.  All I want is random daytime or even night time sex with him.  It makes me feel like he isn't attracted to me while I'm pregnant and we all know how hard that is on us right now.   I'm sure there is another reason why this is happening but for now all I can think of is that he isn't attracted to me.... 😔
