Did anyone get an endoscopy while pregnant?

Hello girls! I had stomach cancer at the beginning of the year which was early detected and cured right away, my doctor said it is fine to get my controls (an endoscopy every 3 months) during the pregnancy. I just want to hear some experiences from other woman. What did you get for sedation? Propofol? Mepiridine? Midazolam? Thanks for any info you can give me, I am a bit nervous about this.
