Big baby or confusion w/ my weeks ? πŸ˜•

Hi girls! I have a doubt. a week ago I did a sonogram, my doctor tells me I have 30 weeks and 4 days, when I did the sonogram was 29 weeks and 3 days. When the doctor saw the results of the sonogram said to be much difference of weeks. my baby is very large, and the result was saying that weighed 4 pounds and 9 ounces, the doctor says that's a little monster if he is of that size. My doctor sent me to a perinatologist, a specialist in high-risk pregnancy doctor. He told me something of macrosomia. macrosomic baby. have you heard that? perinatologist my appointment is Monday. I'm anxious. and I want to know. I love my baby no matter what happens, it's my life. these are the results.
