I had back labours with my last two kids. I didn't have any pain relief, not even gas, due to me being very hard on myself, but I was screaming 'help my back!!!' through the whole thing both times. It seems funny now, but at the time the back pain was so bad I didn't even notice the contractions. I wouldn't have survived without the shower going full force on my back through both labours, first was 24 hours but 8 hours proper labour, second was 10 hours.

The second pregnancy I tried doing all the exercises, whenever I rested, I would rest on all fours. DD spun a few times during labour, but still liked the OP position better than the rest. So they didn't work for me but I've heard many who they worked for. To make things worse, I had a split pubic bone with her, and it hurt like hell through the whole thing, but split when she came out. I found the best way dealing with it was actually moving through the whole labour, lying down was too much pressure on my back.

I survived it and doing it all over again despite the fact I'll probably have another OP one and be silly about taking pain relief again....they are bad but it's the best pain in the world when you look at the result .

Hopefully you'll be fine and it won't be an issue, it doesnt happen too often I don't think, well I haven't heard of too many people having OP labours. But the exercises will help give you peace of mind.
