9 weeks only gestational sac and no baby seen yet.

I had experience this before. Supposedly 9w according to implantation, but when i come for scan, they found nothing! As if i’m not pregnant at all, so they ask me do hcg blood test & must repeat in 2 days if the results doubled means pregnant, if decreased means miscarriage & if go up slowly not even doubled means ectopic! 2days later it turns out doubled, but still cannot see anything but a yolk dot smaller thn 5cents coins, they concluded it’s early pregnancy so instead of 9w i was only 5w, it happened when we ovulating late or something! Why not ask for blood hcg test?

I am at 10weeks and can’t find baby’s heartbeat and measurements say only like 6weeks. Have another appointment next 10days later to confirm baby’s development and discuss for next treatment. Be strong both to you and me. We need to manage our emotions and expectations.

What did the doctor say? How big was the sac? Usually they wait till it’s 25mm to take a call, or the 10 week scan.
