Thank you for your query regarding viability in early pregnancy.
At the outset I'd like to ask you regarding the accuracy of your dates of the last menstrual cycle ( since the last missed period) with the ultrasound report and if there is any specific clinical reason for the ultrasound ( i.e bleeding etc.)
Usually the gestational sac is visualized at 4-5 weeks.
Fetal pole / yolk sac between 5-6 weeks
Fetal cardiac activity 6-7 weeks.
However most gynaecologists wait until 7 weeks gestation or gestational sac diameter of 25mm to comment on viability.
The visualisation of the embryo is also dependant on the mode of imaging. (Transvaginal or transabdominal)
