Aside from blood work, how could i tell if i was starting menopause?

Missing periods: If your periods are starting to become erratic and you know you are not pregnant . Blood work is usually not used to determine whether you are becoming menopausal by most docotors.

1 year no period: Medically, menopause is defined as 1 year without a period. Blood tests don't predict the date of the final period or when 1 year will pass. During the menopause transition, typically in mid 40s to early 50s, periods become increasingly irregular, and symptoms such as hot flashes or vaginal dryness can occur. If these are disruptive, see your doctor.
