I only saw the pregnancy sac at week 6 when I did my first ultrasound & transvaginal scan at KKH. Went back 2 weeks later & saw the yolk sac as well as heard the heartbeat. Might be still early in the pregnancy so the embryo is still not visible.🤗
It’s normal. Usually only can detect during week 7-8. You can go back to check again 2 weeks later.
