Does my baby look to form for 8 weeks?

So the day I had my first ultrasound I thought I was 10w-2d but baby measured 2 weeks behind so that would make baby 8 weeks. I just feel like he/she is to formed to be only 8 weeks :( i compared it to many 8 week ultrasounds and mines look a lot more form.. What do you guys think? You could see my baby's hands and legs already πŸ’•πŸ‘ΆπŸ½ PS: I'm now 11 weeks today 😊
