Don't feel silly - you may not be all that much dilated, but you have started and your cervix is still doing a lot of hard work thinning out and and getting shorter with each contraction. I can vouch for painful posterior births - I have had two of them now. try to do everything you can to get baby to turn to a better postion - all fours, sitting on the toilet with your legs apart (this will make the space at the back of the pelvis smaller, encouraging baby to turn to the front of the pelvis where it is bigger from your legs being apart) and walking - gravity is the key here - so walking, all 4's and sitting on the loo will all help with baby getting in the right possie. And don't forget to rest when you can - make a nest out of a heap of pillows and nestle your belly in the hollow so you can lay down but still keep in the best position.

Good luck - you can do this!!!!
