When I was 17 weeks pregnant, the doctor told me that my baby's left ventricle had an echo nodule 2.6mm thick during an ultrasound. Now I'm 28 weeks pregnant and the nodule is 2.5mm thick. Doctor, can you tell me if the echo nodule in the fetal heart affects the health of the fetus?

Hello doctor, when I was 17 weeks pregnant, the doctor said that I had 2 thick echoes of the left ventricle, but the next time I went, the doctor said it was faint and the next time, the doctor did not talk about 2 echoes. So let me ask if it has any effect and do I need to go and check it again?
