Sometimes problems may occur during pregnancy although everything appeared normal at an early ultrasound scan.
Just under 80% of pregnancies in which fetal heart activity is found at 6 weeks of gestation will continue to term.
Approximately 98% of pregnancies in which fetal heart activity is found at 8 weeks of gestation will continue to term.
This type of measurement is called Crown Rump Length (CRL) and is conventionally used up to the end of the first trimester of pregnancy.
It is also possible to give you an expected date of delivery (EDD).
Reasons to have a first trimester (before 12 weeks) ultrasound scan: – determine the correct site of the pregnancy – determine the gestational age (number of weeks of pregnancy) – confirm the viability of the fetus – calculate the EDD (estimated date of delivery) – diagnose a twin pregnancy – reassurance Viability scan: this scan is normally performed around 6-7 weeks of gestation, calculated from the first day of your last menstrual period or approximately 3 weeks after embryo transfer if you have had IVF treatment.
