Hello Abbys Mum, I have PSD and as far as I'm aware it has no effect on labour except possibly to limit your positions as some may become uncomfortable or painful. A physio would be able to tell you more, or if you google 'symphysis pubis' you'll find lots of info.

One good tip I found online was to put a plastic bag on your carseat so when you get in and out you can keep your legs together and swivel. Can get a bit sweaty on a hot day, but it's saved me a lot of pain!
