You are  29 years old.  So you were born in  1993. Ultrasound came to India in  1980.  But People were becoming pregnant and delivering before  1980.  And there are many Gynecologists who were trained in  1980s and before that. It is only the Ultrasound which can give an assessment of  33 weeks or  34 weeks,  or even  8 weeks 5 days.  The Clinicians  will give a report of  8-10 weeks,  26-28 weeks,  and  so on. So  Ultrasound report will give a precise measurement but  Clinicians will give  approximate measurements. I hope I answered your questions.

Pls attach ur last reports
