Me! Did mine when I was 31 weeks and kitang kita na form ni baby sa 3D ultrasound. We are still waiting for another 8 weeks for our baby's d-day kaya we can't compare hehe. Suggest nila na by 28 to 32 weeks magpa-3D ultrasound para complete na si baby pero possible pa din makita kasi hindi pa masyado malaki. We saw the difference din pala kasi we had a view ng 3D ng face ng baby namin when I did my CAS nung 24 weeks ako.
