Pregnancy Diary Week 13: First Scan

“Please attend with a moderately full bladder for this examination.” As a reasonably intelligent adult who pees several times a day and who has attended two previous pregnancy scans and a routine ultrasound, you would think I’d know how to do that by now, but no.
