Early scan

Hi has anyone ever been to a scan thinking they was about 6 weeks and then theyve got to the scan and no sac? The women said my cervix had thickened up which is a good sign and she thinks im just earlier than we thought. Got another scan on tuesday just wondering if this has happened to anyone else and when theyve gone back for a scan a week later and there has been something there?
