A little bothered

So my best friend has been wanting to go to one of my doctors appointments (I'm pregnant) wel I told her the day I'm supposed to find out the gender and then a few days later she asked if her and my other friend could go also. I wouldn't mind if they went but I feel like there would be too many people in the room (me, my husband, and them) and plus it's kind of a big moment for me and my husband. I don't really know what to tell her.
