Once again, people are discussing fetal development on X like science hasn’t changed in decades. Scientific advances and technology always develop. We saw Klara’s heartbeat on an ultrasound at 5 weeks. People who claim that an ultrasound can’t pick anything up until 8 weeks are behind the times by at least a decade. I saw her heartbeat and I saw her in the summer of 2015 when I was at barely 5 weeks pregnant. Of course, I had a situation with which we are all familiar, and that is why the pregnancy was so closely monitored. But the ability to see the baby and listen to the heartbeat at 5 weeks was already very much there ten years ago.
