Husband doesn’t want to have sex with me

So my husband and I always have a healthy sex life, and he is a very sexual person. We didn’t have sex a lot on my last pregnancy, but mainly I assumed that was because I was on pelvic rest. He acted like that was so hard and he wanted to. So this pregnancy he doesn’t act interested at all. It has been two weeks since we did it and he comes up with excuses if I try. I feel like he isn’t attracted to me, and it’s starting to hurt my feelings. Anyone else’s husband acting this way?? I hope he comes out of it or it goes back to normal after I have the baby at least...
