Age 60 - last period at 56 - first symptoms at 42

At age 42 migraines started and would last 5 days during my period. Nothing helped. Just had to muddle through for 10 years until they stopped. My GP identified that this was a menopausal symptom. Was on the pill until age 54. Not on any supplements or prescriptions for menopause. Some nights I get hot flushes, but no other real symptoms that my friends report. Maybe that is why I was so shocked to receive an osteopenia diagnosis!
