No yolk sac😫

Okay so I’ve been having pain in my right side so I went to the er 2 days ago. I thought I was 5w3d but with the ultrasound they measured me to be about 4w3d which is not that bad. All my pregnancies I’ve been a week off. They did an u/s they saw a gestational sac but no yolk sac they said it might be too early. They did an hcg blood test which I just got back today. It’s 1,154. Which is pretty high for me because my first pregnancy I was at 234 at that time. Is something wrong with my baby? Because hcg levels are high but no yolk sac seen? I have cramping no bleeding. Go back tmm to check my levels again.
