The midpoint
This can be a visually and emotionally significant stage, with new information and new questions arriving together.
Your body
Body shape, sleep, comfort, and movement sensations may change. There is a wide range in when and how these changes are noticed.
Coming up
A detailed ultrasound may be offered around this stage. Ask what it can tell you, what may remain uncertain, and when results arrive.
Appointment companion
Bring the questions you want answered.
Choose prompts for your visit, add your own context, and create a note you can copy or print. Save it only if you want to, and only on your device.
