Pregnant after 6 weeks of dating
By the time the egg reaches the womb, it has become a mass of more than 100 cells, called an embryo.
You ovulate (release an egg) around two weeks after the first day of your period, depending on the length of your menstrual cycle.The purpose of the dating scan is to check: Some abnormalities may also be detected at this scan, such as neural tube defects (spina bifida is a type of neural tube defect).This depends on whether you have agreed to have the screening and when the scan takes place.You may need to have a full bladder for this scan, as this makes the ultrasound image clearer.
You can ask your midwife or doctor before the scan if this is the case. Find out more about what happens during a pregnancy ultrasound scan.This is sometimes called a nuchal translucency scan.
