Hi Sweetie..
That's so exciting that you are getting any type of contraction... I really hope that bubs turns for you though and that the back pains eases.. Maybe check out spinning babies website for some tips on getting bubs to turn... All the other suggestions abount being on your hands and knees and leaning forward are all good for this (I have read a fair bit cause my middie thinks I have a high chance of posterior labour due to placenta being at the front) Good luck Hun and hopefully I'm not too far behing...
Dee xoxo
