I went to my first MFM appt today and they did an ultrasound. Up until this point everything has been fine with our daughter, but when they were done with our ultrasound today..the doctor came in and said that our daughter is on the small side (2.6lbs when should be at least 2.8-3lbs) and that she has some extra amniotic fluid which could mean she has a viral infection!! I am SOOOO FREAKED OUT! I have never had anything go wrong with my previous pregnancy, so I feel terrified! Has anyone else gotten this diagnosis?? The doctor said 95% of the time it is nothing but they obviously have to monitor the baby now..ugh!!! Someone plz give me some feedback 😟😥🙁😣
