TTC#4💗🌈💙🩷🌈

Hi might not have the right group but thought I would try any way I just been for my 20 week scan and she noticed abnormal 3 vessel and 3 vessel trachea view also appeared to be a right sided aortic arch I’m waiting to be seen by a specialist tomorrow but I was just wondering if any one really know what any of that means more so the abnormal 3 vessel thing I’m trying not to google to much but my minds going wild thank you
