Little sympathy from SO

I'm 10 weeks pregnant and have been suffering from morning sickness (severe nausea and chronic fatigue) for at least the past 5 weeks now. My husband seems to have very little sympathy for the way I feel and I feel like he thinks I'm making it up. I haven't been able to go about my usual business because I've been so sick. We had an argument over the fact I didn't go out somewhere with him yesterday was I was feeling so unwell. He's ignored me since and decided to sleep on the couch last night. I'm feeling very upset and anxious that my husband can't be supportive. Has anyone else been through this and how did you cope?
