I'm 38 and for several years now have been feeling warm in bed at night in the few days before a period. Recently this has been getting worse and i am now having full-blown night sweats, whole body dripping with sweat and damp bedsheets. This only happens 3 to 4 days before a period and not at other times of the month. Also i don't have any daytime hot flashes. I know that perimenopause can last upto 10 years before the actual menopause so i could be perimenopausal but surely with me being quite young at 38 i wouldn't be getting meno symptoms quite as severe yet ? Blood tests have indicated that my fertility isn't quite as good as it should be for someone of my age but not impossible to be able to get pregnant. Some of the ladies on the Infertility Board have assured me that these night sweats are normal before a period. Something to do with a rise in estrogen in the 2nd half of the cycle after ovulation i think. I always thought that menopause happened when estrogen levels dropped very low but as i am still ovulating and having periods then surely it can't be menopause ?
