Baby very short

My baby at birth was 18.5 inches long and 6lbs 4oz. I went into to labor at 39 weeks and 1 day. So she was not premature by any means. When I was pregnant I really thought she was going to be so long because I was very uncomfortable for so long she lived in my ribs and my cervix all at the same time. Is 18.5 inches at birth so short? Has anyone else had a baby this short? Mind you I was only 5 lbs 13 oz. At birth but I was at least 20 inches long. At this moment I might be 5'1".
