Do you mean you had an amniocentesis?
Per the physical abnormalities they found at your 2nd trimester ultrasound... I would think it needs to be reviewed by a specialist... or have an amniocentesis if you did not have one.
That is what I did. I was over 35 with my first pregnancy... I had an amniocentesis.. .and ultrasounds. At one point, during the ultrasound, they Doctor said something was wrong with my daughter's heart. We then were referred to a Pediatric Cardiologist, who gave me a more intense ultrasound... and he then found my daughter's heart was fine. She was then born fine and totally healthy/normal. BUT in tandem with this, I had had an amniocentesis... which ALSO confirmed, that my daughter was fine, afterall.
You need to do what you need to do... even if that means more testing. They should have also had you meet with a genetic counselor... that is routine with genetic testing.
I know it is nerve-wracking... but do what tests are recommended... the Doctors are doing their job and following up on any findings that they are not sure of. And it should be discussed with you, and you and Hubby in turn have to discuss it together...
I don't know what tests you are referring to that you had done... you said they checked for all chromosomal deficiencies and all your tests came back "normal." The Amniocentesis is usually done almost near the 2nd trimester, if I remember correctly. To me, this is the most conclusive "test" to check for chromosomal aberrations. An ultrasound will not necessarily pick up these aberrations, and the clarity of the Ultrasound depends on the position of the baby, the shadows etc., because it is all in black and white, and it looks at the physical development of the baby... versus, the amniocentesis analyzes the GENETIC "DNA" make-up of the baby.
All the best to you, discuss any questions with your Doctor...
