Sorry, have I missed something? Your doctor said you're TOO OLD for the menopause at 55?? So, by that reckoning, if you aren't menopausal by the time you are 55, then that's it - you don't have one? It doesn't make sense to me - who happens to be 55 and still perimenopausal (until mid August when I have a hysterectomy - then there'll be no doubt at all!!)
Some doctors need educating!
