Nuchal Translucency Scan

On Tuesday next week, I will be going to my gynae's office for a Nuchal Translucency scan to assess if my baby has a risk for Down's Syndrome. This scan is to be performed between 11 to 14 weeks of the pregnancy. For both my pregnancies, I didn't opt to do any blood test or Amnio to check for Downs and only did the NT scan. My gynae said that the NT scan is quite an accurate marker but not 100% accurate though. Though I'm overall very much relaxed this pregnancy as I know what to expect and handle my discomforts, I am still worried about the scan. I'm worried about all the 'what ifs'. I can only pray that everything will turn out well. Even if this baby turns out to be another girl, I will still be very thankful and happy as long as my baby is normal and healthy.
