acupuncture in pregnancy

Is acupuncture safe in pregnancy? One midwife told me that it is good method to relive the pelvic pain. I think it could be good because it doesn't involve any drugs, which women have to be careful about taking during pregnancy. I don't have any experience with it. I would appreciate some info. Thanks.

I talked with a woman in institute few days ago and she told me that the study shows that methods other than structured physiotherapy may be effective in treating pelvic girdle pain in pregnancy and that acupuncture represents an effective alternative. Pelvic pain which it is thought is caused by hormones affecting ligaments and muscles in pregnancy is often. She said the women using acupuncture experienced the best results.
