I had to go back twice for ultrasounds because they couldn't get good photos of his spine which freaked me out. Over all he just wasn't cooperating with getting the photos but everything was fine
Yup, I had to go back 3 times because my little girl was so stubborn, she was always curling in, lying on the placenta so they couldn't see all the chamber's. Finally the doctor, not the techs, had to come in a do it and it took him like 20 minutes. It doesn't mean anything wrong, your baby is just stubborn lol, my daughter came out perfectly healthy
