Obgyn says hormone levels do not show perimenopause, estrogen high. is this test definitive or could results fluctuate day 2 day with hormone levels?

Regular periods?: If you are having regular periods, you are not perimenopausal. If your periods are irregular, you have hirsutism, and are overweight, you may have polycystic ovarian syndrome. Estrogen levels fluctuate throughout the menstrual cycle. An FSH level is a better indicator of perimenopause, and will become elevated as you enter menopause.
