Had my 20 week appt today. Everything looked well except baby girl was not cooperating with sonogram. The few pics they got of the heart it was hard to see. The dr suggested getting a fetal echo to see if the baby has ventricular septal defect. She reassured us that most of the time it resolves itself within pregnancy. Has this happened to anyone else? First time momma here at 33 so not sure if I should be freaking out yet or not!
