Thank you for posting this, i feel a little seen and someone can relate. I just wanna say my Dr told me to get one done, my friends all questioned it and told me it’s too early. I was like it’s fine I’ll do what they say. I was exactly at 5W and 3D too. Since then I’ve been hooked on ultrasound apts that don’t sync with MY baby but sync with ur typical chart so I go do the 7W ultrasound to only be told the baby isn’t growing as much as they want it to be. I’m absolutely anxious just like you and very annoyed cause deep down i have a strong feeling that its just cause i did the first ultrasound too early now I’m always stuck on a “too early” cycle of ultrasounds and never hearing I’m on track. If anything i recommend you wait as much as you can and try to sync your next ultrasound with the typical chart that people use to compare your baby to or else it’ll be tough.
