I'm am 27 weeks pregnant and had a 4D scan done, the operator said that my baby's Anterior Ventricles are prominent, and that I should discuss this with my OB when I go for my next visit. She has taken two shots , one of something looking like two horns (measuring 3.36cm) and on the opposit side of that something else (which I presumed was the "anterior ventricles") measuring 6mm. My next OB appointment is only in two weeks, but I want to know if this is something I should be worried about? Should I call my doctor for a second apponion or should I just wait until my next appointment? Everything else on the scan was normal. I am still very worried though, please help!
