Good day. Pregnancy is 29 weeks. A month ago, an ultrasound showed one-sided ventriculomegaly. (The size of the lateral ventricle was 10mm). But I had a week before that with a viral infection with high fever. The doctor said to observe. After two weeks after the ultrasound, they admitted me to the hospital for observation (with another problem), and upon admission, they did an ultrasound, the size was 9.3 mm. Today, I had another ultrasound in the same place as the first time, again 10.9 mm. What does this threaten my child's health? And what should I do?
