Hi CLB3
and sorry to hear about your symptoms.
Strictly speaking, judging by your cycles, you are not yet peri-menopausal but at a stage when ovulation is still regular but the last stage before peri-menopause, called the late reproductive phase ( or stage) according to the medical definition. According to that definition peri-menopause is recognised when cycles begin to vary each month by at least 7 days.
However the stage you're at seems to be tricky, ie a sort of pre-peri-menopause because your hormones have begun to go awry and giving you symptoms. As you are so young also, and if you are heading for an early or premature menopause (before 45 or before 40) then you will need to replace oestrogen irrespective of symptoms - though you're probably not likely to hit menopause at 40 if you're still having regular periods now - but you may be well into peri-menopause.
So I presume your doc did the standard tests for FSH, LH etc as described here:
"
Blood tests to measure hormone levels are rarely useful in diagnosing the menopause when it occurs at the “usual” age, but in women in whom Premature ovarian insufficiency (POI) is suspected, then measurement of Follicle Stimulating Hormone (FSH) is useful and, if raised, should be repeated around six weeks later. When the ovaries have failed, estrogen level will be low and consequently, FSH level will rise since its level is controlled by a feedback mechanism involving estrogen. "
https://www.menopausematters.co.uk/pm-investigations.phpI'm guessing that maybe your FSH was not yet raised as possibly expected if still having regular periods?
The important thing is though is what to do about it in terms of treatment? Some women do find a trial of low dose HRT such as Femoston - is helpful at this point, but what could be more indicated is one of the contracpetive pills designed for younger peri-menopausal women. These contain estradiol - ie bio-dentical oestrogenm the same as in HRT and that our bodies produce, but because they suppress the cycle, then the hormonal fluctuations of peri-menopause do not occur. There are to, QLAIRA and ZOELY. Qlaira is tri-phasic and so mimics the cycle a little by giving different doses of oestrogen at different points in the cycle.
You say you've had investigations and I am assuming that other causes of chest pain etc have been eliminated because it is important to know what is causing these.
You are definitely NOT losing your marbles and your symptoms should be taken seriously - to me the shortening of cycles is a give-away and your docs shoud understand this. If you're interested then here is the paper which summarised the different stages - it's quite technical but not difficult to follow:
