You can have regular periods and still be in perimenopause.
According to Canadian endocrinology professor Jerilynn Prior, a midlife woman with regular cycles is likely to be experiencing perimenopause if she notices three of these nine changes:
• New heavy and/or longer periods
• Shorter cycles — less than 26 days
• New sore, swollen or lumpy breasts
• New mid-sleep waking
• Increased menstrual cramps
• Premenstrual night sweats
• New or significantly increased migraines
• New or increased premenstrual mood swings
• Weight gain without changes to eating or exercise
And sometimes the biggest clue is simply:
“The week before my period, everything gets messy.”
One of the women I’m consulting with today described exactly that, brain fog, exhaustion, night sweats, restlessness and feeling like she simply can’t function.
Last month, she bled for an entire month.
This is why we need to stop thinking that perimenopause begins when periods become obviously irregular.
Ovulation can become less reliable while periods continue. Progesterone can decline. Estrogen can fluctuate dramatically, and at times be very high.
Your cycle might still look “normal” on the calendar while you feel anything but normal.
Don’t just track the period.
Track the woman.
