CONFUSED about ultrasound

nelly

Doc says I am about 5/6 weeks but according to last period I should be about 9 weeks, saw the sac is in the correct place but couldnt see much else as Abdominal one didnt show much and tried vaginal scan but my muscles clenched up and started panicking. Have another scan (belly one) in two weeks time but super scared now.

My bloods show an increase and hcg levels are high as they should be.

Anyone experience similar?
