I had three sesions of acupuncture as i was overdue with DD. It does not hurt in any way. the needles hardly even go into your skin. i dont know if it worked casue i ended up having a sweep aswell, but it was so amazingly relaxing and i had a half an hour sleep every time on the table and a good few hours after! i recomend it, even if its just for the relaxation!! but def find someone who is a proper pregnancy specialist! dont just go to a normal acupuncturist. good luck and i hope it works!!!
