I wanted to come on and wish you luck and prayers.
Very good friends of mine, found out they were pregnant and then had some testing done and found out that the baby had Spinah Bifida (not sure of the spelling)
They were upset and the Dr's did scare them. The mom was on pretty much complete bedrest etc.
Well the beautiful baby boy was born and guess what...he is fine, it was a false positive (they had the test done twice and it came back wrong twice!!)
God will be with you and give you the guidance and strength you need. Sometimes if you read too much you get stressed AND then the baby gets stressed.
Take a few deep breaths and wait to see what will happen.
Good Luck to you and your family.
