No :( ifff there is something wrong it isn't your fault a lot of times things are genetic or they just happen not from anything you did! But maybe they just thought they saw something and as a precaution wanted to have it looked at which is good. Hopefully it is a misunderstanding but keep us updated
Is there anything I can do change my diet exercise mor. Something?
My friend just had a baby and he had hypoplastic left heart syndrome and that's what they saw too. Its more common in boys but rare. Not saying that's what it is. Sometimes they look different to one person but don't worry until you have to it may be nothing :) prayers and goodluck
