How many questions are too many to ask at a drs appointment?

I have so many questions for my OB and have been realizing this since my last appointment with them so I’ve started to write them down so I don’t forget to ask at my next appointment but after taking a few minutes to write them down I have like 15 questions already lol! I don’t want to waste their time or make them feel like I’m quizzing them but I also really want my questions answered. Do you ever ask a lot of questions at your appointments with your OB? Should I just save them and ask a few at each appointment? I don’t want to annoy them lol.
