What is gs in pregnancy ultrasound?

GS means gestational sac, it is the first thing seen on an early scan, often around 5 weeks. My doctor said seeing the sac is an early confirmation, and a bit later they look for the yolk sac and heartbeat. So GS is a normal early finding, nothing to worry about.

I remember panicking when my report only mentioned gestational sac. My doctor said it was just early and to come back in a week, and then we saw the heartbeat. So if its only GS for now, it can be totally normal, just early.
