Me and SO hardly have sex anymore

I'm 35+3...I love my SO and our relationship dearly! But our sex life has gone to hell in this last trimester. my SO is afraid to have sex with me because of the baby and me being so far along 😫  there's also been times where sex has been uncomfortable for me, but I still wanna give it try lol. We've  been together for about 7 years and our sex life and everything else has always been great, so this is different for us. I'm just hoping we can get it back after the pregnancy. Any one else currently experiencing this or have in the past?
