Due date changes

Hi, I was just wondering how you change your estimated due date or 'how many weeks pregnant' on this app? I thought I was 12wk 2days & at today's ultrasound they put me at 13wk 1day so I wanted to adjust my details according to that but can't seem to see anything that lets me do that, any tips? Thank you😊 X
