Hi, I had an accupuncturist in NZ who was a GP who went to China and trained in accupuncture and then taught other doctors etc to use accupuncture. She told me that accupuncture is excellent for heavy periods and other problems relating to women's hormones. When she first started, she saw the gynacologists she had trained with, and told them she might be able to help any patients they might be scheduling for hysterectomies just because of heavy periods. So they sent her their patients. She cured almost all of them. The doctors stopped sending them. One time I mentioned that my period was a bit late because I'd been unwell. She put in an extra needle into my foot, and it had begun by the time I went home. So as well as getting a PAP smear test, think about seeing a good well-trained female accupuncturist to see if they can cure the problem. IIt is so tiring and such a pain having heavy periods like that. And it may just be your hormone balance, and no real problem beyond that.
best wishes
