5 weeks ultrasound

Did anyone started like this at either their ultrasound and had a viable pregnancy? I’m not 6weeks as we thought,I could 5 weeks which is fine but the sonographer didn’t really tell me more about it so I’m now stressing the s out aha. She only said my gest sac is measuring 6mm.

From the post I’ve been seeing here most yolk sac are round or pear shape. I’m coming back in 10 days again. 🤞🏼 ( I have underlying issues and my doctor wants to check that everything is progressing okay. I had my last period first day of period back in April 23,2023 and no’s the 7th of June. So I must’ve ovulated late)
