Dont' wish to detract from the people in the know. I have had this problem. I experienced change of life quite early. I did not have a period after the age of 39. This was checked by blood test to see if I was going through menopause, it was confirmed. I do take HRT, at around 46 I had same as you, a period lasting couple of days, and light. I saw my GP who checked this out. He told me menopause does not happen overnight and its a gradual processs, and a period after going so long is not unusual but should be checked. Also that in the early days of starting the menopause you can still get pregnant, if the odd egg or two is still hanging about in the ovaries, thats why we see some elderly people with a downs syndrome child. Because they have not had a period for a while they think its all over.
