Chromosomes 13, 18, 21 and sex chromo

Al
So after all the testing we got and being told our baby has a short nasal bone, humerus, and femur we got the amniocentesis. They told us we would get the results of the 13, 18, and 21st chromosomes within 48 hours. So yesterday I was a nervous wreck waiting for their call. Not only did she tell me that our baby had perfectly normal chromosomes but that we were having a baby boy! Let's just say we've agreed never to do the quad test again.
