Husband not being supportive

So I've had the feeling for about 4 days now that I'm pregnant, but it's too early to test.  I told my husband and he's (understandably) skeptical, I get that he doesn't feel what I'm feeling so he thinks I might be imagining it or whatever (the thoughts crossed my mind too).  However, since I told him he's completely shut down, and since I'm emotional I yelled at him last night about it and made him sleep on the couch.  He left for work before I was up this morning so I haven't talked to him yet.  I guess I'm just looking for some support.  Has anyone else had a similar problem with their SO when it was too early to test?  What did you do?  I don't know how to make it clear to him that I need him to be a little more understanding right now and make an effort to communicate.
