Nervous!!!!!!

Patricia • HALEY 9 💗KELSI 7 💗 BABY ASHER DUE 3-14-15 💙
So I had my first of many third trimester checkup today. I had the luxury of doing the glucose test (yuck) and baby's heart beat sounded great! Well than my ob lays the news on me that at my 23 week scan of my cervix and baby it showed his head measuring bigger than his body!! I'm so scared that theirs and issue or abnormality exspecially since I did the quad test at 13 weeks!! Anyone else have issues like this to relive my fear!! My youngest has a mild form of hydrocephalus and needs no treatment I'm hoping not to go down the road again!
