Pregnancy sex?

Hi ladies and mamas! I will be 27 weeks pregnant tomorrow and my husband and I haven't had sex in about a month and a half! I keep hinting(loudly) to him that it's time but I also don't want to push him. I have brought it up to him but he just seems to brush it off and I don't want to push him if it is pregnancy sex that is what is deterring him away... But I also can't help but feel super self conscious and worry it's cause he isn't attracted to me pregnant.. Any advice or is this normal?
