Obstetric dating scan viability
A pregnancy can be seen from as early as 6 weeks from the first day of your last period (LMP) and not the date of conception.
If the heartbeat is present and the baby measure appropriately for your dates, the risk for having a miscarriage now drops to 1%.
The person performing the scan is called a sonographer.
You may need to have a full bladder for this scan, as this makes the ultrasound image clearer.
Instead, you will be offered another blood test between 14 and 20 weeks of pregnancy to screen for the risk of Down's syndrome.
This test is not quite as accurate as the combined test.
