SO and prenatal appointments

I love my husband very much- but he doesn't know when to stfu. 
This is our third child, and we are still running into the same problem of him taking over my prenatal appointments. He wants to ask all the questions and ultimately distract my dr from what he's doing. It's getting to the point where I can't get my concerns across to the dr because my husband is too busy running the show. 
- I have asked my husband to not attend appointments that are not ultrasound/vital. (Because I felt myself wanting to make appointments that he would be at work for to avoid telling him I was even going!) 
Has anyone else experienced this?
