pregnant 9weeks

Aah, don't worry la, size discrepancy at 9 weeks is quite normal actually, some babies measure a bit smaller or bigger than expected based on period dates je. Tapi since ada difference between scan measurement and your LMP calculation, best la you mention this to your doctor next visit and let them monitor closely, because sometimes dating bisa off sikit depending on cycle length or ovulation timing masing-masing orang lain, so doktor boleh adjust your due date if needed based on scan findings which is more accurate anyway.
