I have had that ultrasound twice already!! Now I have to go to a specialist to get it done again

Yes I had,something like this but instead one of my blood test came back high for Spinal B and I had to get a level 2 ultrasound. I had to wait 2 week for the appointment It was so stressful but thank god she was fine. All the level 2 ultrasound is a longer and more detailed ultrasound they look at every part of the baby. So do not stress they are just double checking because they can fix this stuff in the womb with less complication after birth. So they just check even if there is a low percentage. hopefully this helps
