Yes. Your baby's fetal weight appropriate for the gestational age. The 50th centile for 20 weeks and 2 days comes to 350gm on the fetal weight graph. I think you mentioned 360gm (it is not mg). So it is on or above 50th centile. so no need to worry. Its normal for that age. In anamoly scan the doctor will plot the weight and other parameters on the graphs. you can have a look in that also. anything on the 50th centile(middle line) is normal. Hope your doubts are cleared. All the best.
