Hi there, I have understood your concern and I will suggest you the best possible treatment options.
First of all do not panic.
This USG report is showing fetal growth corresponding to the period of pregnancy
as on today can change to vertex presentation by 34 weeks.
Secondly, baby weight is also corresponding to weeks of pregnancy.
At around 28 weeks, baby weight gets closer to 1kg.
I will suggest you not to worry.
Opt for a healthy diet and regular exercise regimen.
Include more portions of fruits and vegetables and salads in daily diet.
Drink plenty of water in the day.
Have regular intake of Folic acid
, vitamin B 12, IRON, Calcium and protein supplements
Practice deep breathing.
May God bless you with a bundle of Joy.
I hope this answer helps you.
