Hello, Ladies. I could use some advice. I am currently pregnant from an IVF cycle. I was originally pregnant with twins, and one has since vanished. The other seems to be thriving. As a result of all of this, I have been heavily monitored and have had several scans. I am now back with my regular OB. He had me come in Monday for a Nuchal scan, but I was only 10w 6d, and the tech was unable to do the Nuchal because it was a few days too soon. My OB then had my blood drawn for the MaterniT21 test. He has me scheduled for another ultrasound in 4 weeks, when I will be 14w 6d. All of my research has shown me that this is far too late for an NT scan. When I mentioned it to my Doc, he said it was fine, as the MaterniT21 test is far more conclusive anyway. I am wondering if not having a proper NT exam is a bad idea. I am almost 39, and so at higher risk for chromosomal abnormalities. If the MaterniT21 comes back fine, then does the NT scan really become irrelevant? I just want to make sure that I have all of my bases covered, and that every available non-invasive test is used. Then again, if it is really unnecessary, then I guess I shouldn't worry. Any thoughts?
