Tanny, 6wks, 8wks, 12wks -DS scan (pls dun do the test earlier than that coz bb grows at different rate n can create false alarm. KKH AMC will schedule for u, just tell them, u wan scan at 12+wks, do the scan a few days before the last allowed date) then see gynae at 15-16wks, then full scan at ADC at 19+wks & you will see ur gynae on same day to review the full scan report.
There is a DS blood test before the scan. Same thing, dun do to early. Ask the nurse to schedule 1 wk before DS scan. U will know the combined results, BT & scan on your day of scan. Request for a report to safe keep at no charge. that is your copy.
If not, AMC will schedule BT as early as 9wks n the scan at 11wks. That is my lesson learnt from first pregnancy.
