Husband not attracted to me 🙃

So since I’ve gotten pregnant, my husband has so far still been pretty intimate. We obviously aren’t having as much sex as we used to because I’m tired all the time lol but we were still managing like two to three times a week. Now that I’m really showing, it’s like he’s not interested anymore. This is our first baby so I’ve never been through this. But I’ve been trying to jump his bones for two weeks now & he always has some weird reason not to have sex. I’m starting to worry. I brought it up & he dismissed it like I was being crazy. Any other pregnant ladies gone through this?
