FHR : 160 bpm The fetal biometry are as follows BPD : 75.59mm (30 weeks) HC : 289mm (30 weeks 4 days) AC : 266mm (30 weeks 4 days) FL : 55.03mm (28 weeks 4 days) Fetal weight is 1542 gms My queries are: 1. Can gestational age be 2 weeks/ X weeks ahead of menstural age? Is this normal? 2. Is HC too high for 28 weeks? What does high HC mean? Does high HC mean any disorder or diffeciency? Note: I don t have any family histroy for any disorder or diffencieny. 3. Is my baby over weight for 28 weeks? 4. Does the biometry report seems to have normal reading or is there anything alarming?

hi there, after 24 weeks of gestation a difference in the gestational age by LMP and by USG can be +/_ 2weeks and it is normal to see these variation. The biometry is not alarming and does not indicated any abnormality in fetal growth or weight. Relax and take care.
