Ultrasound worries

Brianne
So I had an ultrasound done this past Monday when I was 12 weeks 2 days and they had said everything looked great. But then the doctor came in and told me that something had caught her eye, she said it looked like possible Gastroschesis. It is still too early to tell 100% I have another ultrasound at 14 and 16 weeks to check again. 
 Has anyone had this happen during their ultrasound and if it is Gastroschesis what was your experience?
