Anyone have experience with these? I had my anatomy scan today, and my baby has two cysts on his brain (I'm exactly 20 weeks). My doctor said everything else on the scan looks perfect, so that I shouldn't worry (and that they see these often). He didn't even mention possible issues. I made the mistake of googling what these are, and now I am panicked that something is wrong with my baby (specifically trisomy 18). Anyone have experience with this?
