Am I pregnant?

Shelbie
My last period was a little over two weeks ago, but it was late, very short, and very light. I've been sick every morning for the past week and a half or so. I've never been pregnant before, so I'm not sure what to expect/look for. I was going to take a home pregnancy test but it said you have to wait till 4 days before your missed period so I haven't taken it yet.
