Has anyone else been told their child has a “hip click”?

The doctor gave me three options.

1) to get an ultrasound done to be sure the hips aren’t dislocated

2) to see this specialist at a children’s hospital or 3) to wait it out

I’m not too sure which option I am going to choose yet, but if they are dislocated what will they do from there? If they aren’t, what would be the cause of the hip click? I myself have a hip click and believe I was born with it. My hips are not dislocated, but are uneven. Meaning one leg is longer than the other, nothing too extreme though. I would love to know anyone else’s experiences with this.
