Hospital bag!!

Hiya everyone, I’m 33+4 today (due date is 1st Nov but I look in this group too).... This is my first pregnancy and I’m not sure when to pack my hospital bag?

I have a bag ready and most of the stuff needed to pack into it, but when’s a good time to pack?

I’ve just recently (last week) started to help out a friend on the afternoon school runs 2 times a week, meaning each day I’m walking around non stop for around 2 hours by the time I get back home. On the way back home I get uncomfortable at the bottom of my bump/top of groin/in my back too. I’ve read that doing exercise can bring on labour so would you all recommend I pack it sooner rather than later just incase?

I should probably add that since March I’ve not done much exercise compared to what I used to do before being pregnant (I lost my job) so it’s probably a bit of a shock to my body.
