Think as much as you can, your body will tell you when it’s too tired to continue! Just make sure you’re walking in a loop/ somewhere that if you do get tired you can quickly return to base from! I was going on hour-long walks from 37 weeks to try and help but now 39+2 and can’t walk for more than five minutes without being in pain or out of breath x
Walk as much as u can I am in labour ward amd I've been walking in the whole hospital every 2 or 3 hour for half an hour and doing some squat and bouncing on the ball. I get contraction after I lie down
