When we went to our 20 week scan they looked at everything, organs,borns,head,etc and sent us on our way.... when we were there though our sonographer was pulled away to have a look at someones elses ultrasound because they wanted a 2nd opinion. She came back looking down and said not all scans are happy scans.... obviously someone else was getting some bad news. that was at the hospital in NSW (sydney) So Im guessing they'd tell you if something was wrong (especially so you could consider your options asap , being that its the easter long weekend....

Sounds like everything with your bub is FINE Relax and have a happy Easter
