Is anyone else less attracted to their S/O now that you're pregnant?

I'm just not feeling the same way about my man... he's my fiancée and we have gone through a lot. !!  I'm the breadwinner and it just feels like everything about him is bothering me lately!  I almost want to do this alone!
Any married women who can help or may have had similar feelings of contempt with her man while pregnant?  Does this go away?
