Hi. I am 40 years of age. My periods are very regular, like clockwork, they come every 26/27/28 days and can be timed easily enough. I usually have a consistent level of pain, which is very managable. However, 2 months ago a change occured in that it came on day 24, and much to my shock, this month it come on day 18, with no pain whatsoever, and lasted longer than normal. Recently over the past few months I have had sweating issues especially at night, whereas usually im a cold ish person. My weight is 9st and my height is 5ft 3inches, all very normal. I have no children. I am a healthy person also with a good diet , and daily exercise. What should I do, as I fear this may be something to do with early Menopause . My husband and I are hoping to try for a baby very soon too.
