Anatomy Scan this week!

I’m having my anatomy scan on Thursday this week- I’ll be 19w1d. It seems early to me based on when most other people have talked about having their scan, but it’s when my midwifes office booked it 🤷🏻‍♀️. I’m really excited because it will the first time I’ve seen my baby since the first ultrasound at 7w3d confirming my pregnancy! Does anyone have any tips on what to expect or how I should prepare myself? No one from my office has said anything about going with a full bladder, though I’ve read that other people recommended that or were told that by their doctor.
