My DP was unimpressed by my night time epiphany so I thought I would post it on here instead
Was thinking that due dates are a PITA, usually always inaccurate - sometimes wildly so, and people just get stressed if they are "early" or "late".
Would it not be better if you were instead given a Best Before Date, a kind of advisory date (like on food) that suggests that if you go beyond that date you may need additional monitoring - for most would be 42 weeks but could be varied on circumstances. Seems to me would avoid a lot of stress.
Feel free to ignore post - just wanted to share my great idea
