Transvaginal ultrasound and do not understand results :(

[Sassyislife]

I had a transvaginal scan yesterday as I had been experiencing some pain and some bleeding, after having a miscarriage last year this all panicked me.

From the dates I have worked out I am 5 weeks + 5 days meaning yesterday I was 5 weeks + 4 days, the scan showed nothing but the gestational sac, no yolk or anything else, which i understand is normal this early, but from what I have read on google the size of the sac is smaller than it should be?
Im not 100% sure on how big the sac should be and I dont really understand the sizes can anyone give me some reassurance? or just tell me if its too small or not? And if my hcg levels are normal? I have another scan in 10 days to double check things. I am absolutely terrified guys, I really want this to go well
I have attached picture but if isnt visible -

Gestational sac size: 3mm x 1mm x 3mm
Gestational sac (mean) 2.3 mm
HCG Levels: 1678 mIU
Progesterone Levels: 49.30 nmol/l.

Thank you

I am not an expert but it sounds like a reasonable result for being so early. The measurements are so tiny at that stage that measurements are not always perfectly accurate. I mean we are talking mm here, not cm. It's really easy for them to be a mm out. Also having ovulated a couple days later than you thought could make a big difference to measurements. And some babies seem to be faster than others implanting. DD measured almost a week ahead on my first scan which I knew was impossible so I don't think their dates are always as accurate as they think .

The fact that they found a sac in the right place is the important part for now. They will be able to tell much more at your next scan, at least I assume you are getting another one because that is what the paper is recommending. I won't tell you not to worry, because I know that is impossible!
