I had an abdominal ultrasound today and all we could see was the gestational sac, it was a private clinic that just opened, they said I am around 5 weeks, but my LMP puts me around 7 weeks, I have read online that the earliest an abdominal scan would show the gestational sac is 7 weeks so this corresponds with my LMP, with an abdominal scan when is the earliest you’d see the gestational sac and yolk sac/embryo
