What do I ask my doctor?!

Okay ladies, I havent seen my doctor in probably 3 appointments. I've been seeing her sub since shes either been on vacation or delivery. BUT I didnt have an appt last month like I was supposed to and I'm finally seeing my actual doctor today. Since I havent seen her, I've had my 20 week ultrasound, my glucose test AND have started my 3rd trimester. As you can see it's been a bit since I've seen her. It's been probably since I was 18 weeks and now I'm 28 weeks.. What kind of questions should I ask her? I have so many but pregnancy brain has got me bad right now. My appt isn't til 3 so I have a little time to get stuff wrote down. I know I'm definitely asking about my 20 week ultrasound. It came back normal, but the sub didnt give me any specifics or answer any of my questions. Thank you advanced
