My menses causes so many aches and pains now when before was younger i really never suffered any prob with it? why now? heavier bleed, stomach issues

Heavier menses: Many things change as you drift toward menopause. As long as they are regular, there is probably little need for concern.

Age related risks: Your age puts you at greater risk of having various uterine growths such as hyperplasia, polyps, or fibroids that can worsen your bleeding profile at your age. You may need a biopsy and/or imaging.
