You don’t know, until you know. Poo
Just before I had my first baby I saw a nutritionalist for a range of reasons, mostly because I was super neurotic. The very best piece of advice I was given by this nutritionalist was this - in the week before baby is due, start taking a gentle laxative. No matter how you give birth, the first time you poo is a daunting experience. You’re using parts of your body that have already been given a fair workout over the past few days, and if you’ve had any sort of stitching there is a whole lot of mental barriers to overcome too. I didn’t know this until I knew it…. so try and stay as hydrated as you can and take a gentle laxative that your health professional approves of.
