I also attached my 8 week ultrasound to show the difference. I had these done at a local 3D/4D clinic and at 8 weeks she was able to find the baby’s heartbeats a strong 180bpm but then at my 10 week, she couldn’t find the heartbeat and was having trouble getting a good view of the baby. Is it possible the baby was just hiding and she couldn’t get a good angle for the heartbeat? Should I be worried? I’m calling my OB Monday morning but have been freaking out until then.
