She has an EIF

Sarah
Well on Dec 9th at our anatomy scan they told us they saw an EIF (shadow) on her heart and we'd need to see a Maternal and Fetal Medicine specialist. Well our appointment is in about 7.5hrs, I can't sleep (it's currently 1:38am EST) and it's an hour drive to the specialist. Has anyone else been told their baby had an EIF? If so what happened? Oh and our genetic testing came back negative for anything they test for such as downs.
