My high school friends and I \u2014 a gaggle of 40-somethings \u2014 were on a long-anticipated midwinter trip to the white sandy beaches of Naples, Fla. when my period hit, unexpectedly and with a vengeance. Luckily, I had a just-in-case tampon in my travel kit. (Perimenopause pro move!) The weird thing was, the\u00a0heavy flow<\/a>\u00a0continued beyond the usual five days, then beyond seven \u2026 then beyond 10. Only after a full 14 days (!) did it finally leave as abruptly as it had arrived. WTF? So much for being a “peri-pro.”<\/p>\n

That’s the reality of\u00a0perimenopause<\/a>\u00a0in your 40s: Your ovaries start phoning it in, forgetting their rhythm and throwing hormones like estrogen, progesterone and testosterone all out of order. Sometimes your period goes missing, sometimes it barges in like a houseguest who overstays and eats all the snacks.<\/p>\n

And periods are just the beginning. Perimenopause in your 40s can mess with your\u00a0sleep<\/a>, mood, skin and even your joints \u2014 which is why perimenopause is often described as the “wild ride” before\u00a0menopause<\/a>. Here’s what’s really going on in this stage, and how to get some control back.<\/p>\n

 <\/p>\n

When does perimenopause start and how long does it last?<\/strong><\/h2>\n

Perimenopause, officially called the “late reproductive stage<\/a>” is basically the long on-ramp to menopause. It begins when estrogen levels start to decline and your period is\u00a0consistently late or early by seven days<\/a>. For some women this\u00a0happens in their mid- to late-30s<\/a>. For others, perimenopause kicks into full gear in their early- to mid-40s, and it can last about eight to 10 years, says\u00a0Dr. Sherry Ross<\/a>, a board-certified ob-gyn at Providence Saint John’s Health Center in Santa Monica, Calif. That tracks, since\u00a051 is the average age of menopause<\/a>\u00a0in the U.S. (Learn more about the difference between perimenopause, menopause and postmenopause<\/a>.)<\/p>\n

What are the most common perimenopause symptoms in your 40s?<\/strong><\/h2>\n

Unlike other midlife transitions, like the slow creep of\u00a0wrinkles<\/a>\u00a0and\u00a0graying hair<\/a>, perimenopause can sometimes come in like an unexpected tornado. “During perimenopause, your body has to crank hormones higher to recruit eggs, which leads to bigger peaks and deeper troughs. It’s almost like PMS on steroids,” says\u00a0Dr. Robin Noble<\/a>, an ob-gyn and chief medical officer of\u00a0Let’s Talk Menopause<\/a>, a nonprofit working to improve menopause care.<\/p>\n

Of course, “everyone has a different experience and different severity of symptoms,” says Ross. My perimenopause symptoms may feel intense, my friend might say hers are totally manageable and that annoying lady down the road might be all “I still feel 22!” No matter, low estrogen levels lead to lots of symptoms, not just “period stuff.” Here are some of the most common perimenopause\u00a0symptoms in your 40s<\/a>:<\/p>\n
