Hi so I went for my 20 week ultrasound and this what it looks like. Doc didn't say anything other then he thinks I'll give birth in January instead of February. My son has a brain birth defect that went unnoticed till he had an MRI. And my ob didn't catch on to his Brain birth defect at all. Does this ultrasound look normal for 3D? My mom said how it looks like masses instead of a normal head for the baby. Can't even point out the eye sockets or anything of that matter. Heart rate was good at 156 bpm.
