Girls, hello everyone! I literally wrote yesterday that I feel little movements, today I went to listen to my baby and thank God everything is fine, just the little one turned his head down and the movements became weak to feel, the only thing they said is that there's a hyperechoic focus in the heart visible, but it's nothing scary, supposedly it will pass by the third ultrasound, but exactly a week ago I had a second screening at the molecular medicine center, and nothing like this was mentioned close by, can you please tell me if anyone has experienced something similar? How critical is it? My gynecologist said it will pass on its own, but she didn't give any recommendations. Thanks in advance!
