Never in my life was I not on time with my period... unless I was pregnant. Now I have it every 3 weeks instead of 4 weeks. Why is it changing? Should I worry? I'm 47
There are two reasons for early period. One is heat or damp heat (profuse, dark-red, thick flow or with clots). The other is qi deficiency (light red, thin menses flow with shortened cycle, lassitude, and dislike of talking). All acupuncturists know this very well. Premenopause or menopause leads to delayed period most cases. Her age is close to menopause, but symptom is different. Go to acupuncture clinic soon.
