Help me please

I recently found out I’m pregnant. I am sick and constantly tired. I haven’t been in the mood to have sex for awhile due to my body aching and exhaustion. Well my boyfriend is claiming I’m cheating on him because I haven’t slept with him in about a month. I seriously have tried explaining that I’m not feeling good at all and don’t want to have sex in his car. That and two he literally controls everything I do. He made me take a few pictures off Facebook because I was in a tank top. Everything was covered up but he still yelled at me. Is it bad that I don’t want to have sex? Is it normal not to have a “sex drive”. I’m about 9 weeks
