Hi again Sophiaflorance
Yes there are others on here who have had a later menopause - in fact was a thread on here started by Machair...
I'm sure you don't need me to tell you that if you are overweight (by that I mean BMI above normal range and the extra weight being fat not muscle) then the best thing you can do for your future health as you approach menopause and beyond is to start on a path to try to reduce this little by little, and increase exercise - if you are able to - I know can be easier said than done but if you are able to make tiny changes....bit by bit.... Do make sure you have had thyroid tests if your weight gain is fairly recent - as some women develop underactive thryoid at this stage, which can cause weight gain. Being overweight and especially if obese is a strong risk factor for several cancers, including breast and womb.
Re reducing oestrogen and excess weight - yes you are right - that when we are post-menopause our fat cells produce oestrogen so a way to reduce these levels is to lose weight - so if this is what you mean by diet then yes! As far as I know though, this won't have any effect on ovulation and menopause as this is under control of the ovaries and brain - once your ovarian reserve has declined and you gradually cease to ovulate then you won't produce oestrogen by that route - but still produce some from fat cells.
I can understand your worry at your age ie whether the bleed is normal or not but the good thing is, due to your age the docs are checking just in case, so i would welcome the two week pathway as it means nothing sinister should slip through the net. Carry on being vigilant but try not to worry!
