One day, you’re going about your life as usual, and the next, you’re Googling “why am I so angry all the time” at 3 am while simultaneously sweating through your pajamas and craving carbs. Your period arrives whenever it feels like it, your jeans stopped fitting sometime last month, and you just burst into tears watching a dog food commercial.
Welcome to perimenopause—the hormonal rollercoaster nobody properly warned you about. If you’re nodding along thinking “is this what’s happening to me?”, you’re definitely not alone. Let’s talk about the telltale signs that your body is gearing up for menopause.
1. You’ve become a human furnace.
The hot flash is probably perimenopause’s most well-known calling card, but nobody prepares you for how intense and disruptive they actually are.
It often starts as a wave of heat rising from your chest to your face, and suddenly you’re desperate to rip off all your clothes in the middle of a work meeting. If you’re particularly unlucky, your face might flush visibly, prompting concerned colleagues to ask, “Are you okay?” while you’re frantically fanning yourself with whatever’s nearby.
Night sweats are equally brutal. If you’re anything like me, you’ll wake at 2 am absolutely drenched, sheets soaked, having to change your pajamas and sometimes even the bedding. Meanwhile, your partner (if you have one) is sleeping peacefully under a duvet, completely oblivious.
For me, the hot flushes were the worst symptom, since I already struggle with temperature regulation from hypermobile Ehlers-Danlos syndrome (hEDS). Until I started HRT, I frequently stood outside in winter wearing just a t-shirt while everyone else was bundled in coats, getting strange looks but honestly not caring because the alternative was spontaneous combustion.
Of course, HRT isn’t for everyone. It’s a personal choice, with valid reasons for and against. Hats off to you if you manage to battle through hot flushes without it, because there’s no way I could.
2. Your brain has left the building.
Perimenopausal brain fog can be especially crushing, particularly if you’re someone like me who has always prided themselves on their memory, attention to detail, and organizational skills.
You’ll walk into rooms and completely forget why you’re there. Mid-sentence, words just vanish from your brain—”you know, the thing, the thing, that thing that we use to do the thing…! What’s it called?!”
You miss appointments despite having multiple calendar reminders. You re-read the same paragraph five times and still can’t retain the information. I once introduced a close friend using completely the wrong name—not even a similar name, just… someone else’s name entirely. The shame was real.
And don’t get me started on how devastating this cognitive decline can be if you already have a condition or neurodivergence, such as ADHD, that causes brain fog. The coping strategies that worked for years suddenly stop working as estrogen drops. You feel utterly incompetent despite your very best efforts.
As a side note, there’s actually some really fascinating research coming out around perimenopause and ADHD: during this time, many women are beginning to discover they have undiagnosed ADHD. It’s one of the reasons ADHD diagnoses appear to have skyrocketed. The brain fog becomes so severe that it reveals underlying attention issues that were always there but previously manageable. If you’re suddenly struggling dramatically more than expected, and the cognitive issues feel like more than just “forgetting words,” it might be worth exploring whether ADHD has been quietly lurking beneath the surface all along.
3. Your mood swings could power a theme park ride.
One moment you’re absolutely fine, the next you’re furious about something trivial, and five minutes later you’re crying at a commercial about toilet paper.
The rage is often what shocks women most. It feels disproportionate to whatever triggered it—someone chewing loudly, a slightly annoying email, spilled milk—but the fury is real and overwhelming. You know you’re overreacting even as it’s happening, but you can’t seem to stop yourself.
Then there’s the crying. Animal videos, sentimental songs, and even a barely touching scene from K-pop Demon Hunters (that you’re only watching because your kids are, obviously).
The irritability makes you unrecognizable, even to yourself. You snap at people you love over nothing. Your kids and partner start walking on eggshells, which makes you feel worse because now you’re “that person.” You apologize, you feel terrible, you promise yourself you’ll do better, and you do try. Hard. But then the hormones surge again, and it happens anyway.
4. Your periods (might) have gone completely rogue.
Remember when your cycle was predictable? When you could plan holidays, white pants, and important events around a menstrual calendar that actually made sense? Those days are probably gone.
The erratic production of estrogen and progesterone turns your period into a chaotic wildcard. You might have a 21-day cycle followed by a 45-day stretch of nothing, then surprise—two periods in one month. The flow is equally unpredictable: some months you’re dealing with a crime scene that has you Googling “how much bleeding is too much bleeding,” and other months it’s barely-there spotting that makes you wonder if it even counts.
Your period tracking app has essentially given up, showing predictions that bear no resemblance to reality. And there’s the constant underlying anxiety of “am I pregnant or is this just perimenopause?” even when pregnancy isn’t remotely possible.
There’s an important caveat you need to remember, though: you can absolutely be in perimenopause even if your periods are still relatively regular. I experienced many of the other symptoms before irregular periods. Not everyone experiences menstrual chaos right away. Yes, irregular periods are common, but they’re not the only indicator, and they’re certainly not always the first.
5. Sleep? What’s sleep?
For many people, the cruel irony of perimenopause is feeling bone-tired but completely unable to stay asleep.
Perhaps you fall asleep easily enough, exhausted from the day, but then—bam—you’re wide awake at 3 am. Your brain suddenly decides this is the perfect time to replay every embarrassing thing you’ve ever said, solve complex work problems, or worry about things that haven’t even happened yet.
Sometimes it’s the night sweats jolting you awake. Other times it’s that you need to wee for the millionth time. Often, there’s no obvious reason; your body just decides sleep time is over.
The next day, you’re a zombie, barely functioning, relying on coffee to string coherent sentences together. But come bedtime, despite being exhausted, the cycle repeats.
You may have tried everything: magnesium supplements, meditation apps, sleep podcasts, blackout curtains, no screens before bed, chamomile tea. Some things help marginally, but nothing reliably works.
And often the worst part is that the sleep deprivation compounds everything else—you’re less patient, more emotional, foggier, and less able to cope with the other symptoms.
6. Your metabolism has changed, and not for the better.
If you’re someone who has always had a relatively stable weight or been able to eat a relaxed diet without worrying about weight gain, this one can come as a shock. You may find you’re eating the same foods you’ve always eaten, exercising the same amount, and yet somehow you’re gaining weight—particularly around your middle.
Clothes that fit last month suddenly don’t zip. Favorite jeans that were comfortable, now cut into your waist. It’s frustrating because nothing has changed on your end, yet your body is responding completely differently. That metabolism that hummed along reliably for decades has apparently decided to take early retirement.
You need to eat less and move more just to stay the same weight, never mind actually losing any. The unfairness of it is maddening. What’s more, diet culture and gendered ageism make everything worse.
Yes, continue prioritizing movement and nourishing foods for your health and well-being. But also? Cut yourself some slack. Your body is changing, and that’s a normal part of aging. Aging gracefully doesn’t mean defying the process. It means accepting that your body at this stage of life looks different, and that’s okay.
7. You’re suddenly an anxious mess.
If you’ve always experienced anxiety but gotten by, you may find that perimenopause sends it into overdrive. And if you’ve never struggled with it before, you may be surprised to find it seemingly appears from nowhere.
You might notice that your heart races for no reason. Your chest feels tight. You may experience a sense of dread or impending doom that you can’t shake, even when logically nothing is wrong.
For some people, this can turn into catastrophizing—your partner being quiet means they’re leaving, a work email asking to chat obviously means you’re getting fired, minor headaches become brain tumors. Everything spirals to worst-case scenarios. Quite frankly, it’s only natural that health anxiety would intensify because you’re experiencing so many weird symptoms. Is this perimenopause or something more, you might ask yourself?
Social situations that never bothered you (or only mildly bothered you) before might suddenly feel overwhelming. You second-guess everything you say, worry about how you’re coming across, feel self-conscious in ways you haven’t since adolescence. And of course, this is only made worse by the complete inability to string together a coherent sentence.
Not enough women realize that anxiety is a common perimenopause symptom, and medical misogyny doesn’t help. So they suffer in silence, assuming they’re just being “oversensitive,” missing out on both vital validation and support.
8. Your joints and muscles feel like they’ve aged 40 years overnight.
Aches and pains are another lesser-known symptom of perimenopause. You may find that your joints are stiff and achy, particularly in the morning. You wake up feeling like you’ve aged several decades while you slept. Getting out of bed requires an actual strategy and possibly some audible groaning.
There may be new aches in places you didn’t realize could ache. Your hands feel stiff. Your feet hurt. Everything just feels… creaky.
The reason for this is that estrogen has anti-inflammatory properties and helps maintain collagen in your joints and connective tissues. As estrogen declines, inflammation can increase and joint lubrication decreases, leading to stiffness and pain. This is a genuine physical change, not just “getting older” in a general sense.
This can be particularly brutal for those of us who already have health conditions that cause chronic pain. Personally speaking, it feels like no matter how much I move anymore, I can’t ever seem to shake the stiffness out.
The disconnect between how old you feel mentally versus how old your body feels physically is both jarring and demoralizing.
9. You’re extremely tired but weirdly wired.
There’s a specific kind of fatigue that comes with perimenopause that’s different from ordinary tiredness—it’s deeper, heavier, like you’re moving through mud. If you’ve ever been pregnant, it’s a little bit like those early first-trimester days.
You’re absolutely exhausted, running on empty, desperate to rest. But simultaneously, thanks to the anxiety and racing thoughts we already mentioned, there may be this restless, wired energy coursing through you that won’t let you actually relax or switch off.
It’s like being bone-tired but unable to sit still. Your body is screaming for rest while your nervous system is revved up and jangling. You crash on the couch but still scroll your phone endlessly because you can’t actually settle.
This often connects to the sleep issues, too. You’re tired enough to sleep but too wired to stay asleep. The adrenaline and cortisol spikes keep you on edge even when you desperately need to wind down. Some days I’ve felt like I could sleep for a week, while simultaneously feeling agitated and unable to truly rest. It’s an exhausting paradox.
10. Your hair is either falling out or growing in weird places (or both).
You may have seen a lot of hair in your shower drain and been genuinely alarmed. “Is this normal shedding, or are you going bald?” you may ask. Perhaps your parting looks wider and your temples seem thinner (mine definitely do).
What’s more, your hair texture might be changing too. During perimenopause and menopause, it can become coarser, drier, more wiry, or just generally less cooperative than it used to be. Hairstyles that always worked suddenly… don’t.
And then, as if losing hair from your head wasn’t enough, it starts appearing where you absolutely don’t want it. Chin hairs. Thick, dark, surprisingly long chin hairs that seem to sprout overnight. Your eyebrows are thinning while your chin apparently thinks it’s auditioning to be a beard. The injustice of it all. I’ve lost count of the number of times I’ve discovered a horrifyingly long chin hair after being out all day, and immediately wondered how many people had seen it and said nothing.
Though it’s all a natural part of aging, the way society views femininity can make it hard to accept, even for the most self-assured and unapologetically authentic of women.
11. Your libido has gone on an extended vacation.
Your sex drive can plummet during perimenopause, yet it’s one of those symptoms many people feel uncomfortable discussing.
You might go from having a healthy interest in sex to suddenly feeling “please don’t touch me” when your partner initiates intimacy. Or your desire becomes so unpredictable that you can’t anticipate how you’ll feel from one day to the next.
There’s often guilt around this, especially if you’re in a relationship. You feel bad for not being interested, worry your partner takes it personally, and might even feel pressure to engage when you really don’t want to.
Physical changes don’t help—vaginal dryness can make sex uncomfortable or painful, which naturally affects desire. It’s hard to want something that hurts. The reason for these changes is that estrogen and testosterone both play roles in sexual desire and function. It’s not psychological—there are real physical and hormonal reasons for these changes.
The disconnect between wanting to want it but just… not, is both confusing and frustrating. You may remember enjoying sex, you think you should want it, but the desire just isn’t there. It’s normal, but that doesn’t make it any easier for you to deal with.
12. Your skin suddenly rivals a teenager’s during an acne outbreak, only with added wrinkles.
Declining estrogen affects your skin’s oil production, collagen levels, and healing capacity. It can trigger increased androgen activity (similar to puberty), causing breakouts. Meanwhile, less estrogen means less collagen and elasticity—so you’re essentially left dealing with wrinkles and pimples at the same time. Ugh.
Breakouts typically appear along your jawline, chin, and neck. These are the classic hormonal acne zones. You may find they’re deeper and more painful than teenage spots, taking longer to heal and sometimes leaving marks.
You might also find that your skin is suddenly drier than it’s ever been. The skin you learned to manage years ago has transformed into something entirely different that requires a complete skincare overhaul. Products that worked reliably for years suddenly cause irritation or just stop being effective.
Your skin texture changes too—it might look duller, feel rougher, or lose that plumpness it once had. If you wear makeup, it starts to sit differently, settling into lines you’re sure weren’t there last month. You’re essentially starting from scratch, trying to figure out what your new skin needs.
13. Your tolerance for BS has completely evaporated.
Ok, so you won’t find this listed among the official medical symptoms associated with perimenopause, but something shifts during this time—suddenly, you have zero patience for things you used to tolerate. You may find yourself speaking up about things that always bothered you, but you previously stayed quiet about.
There’s a strong “I’m too old for this” energy that can feel both liberating and slightly alarming. You’re not suffering fools gladly anymore, and while that’s somewhat empowering, it can also strain relationships with people who were used to you being more accommodating.
This connects to the mood swings and irritability we talked about earlier, but it’s also something more—a genuine shift in what you’re willing to accept. Admittedly, though, there’s a fine line between healthy assertiveness and hormone-fueled rage. Still, perhaps this is one perimenopause “symptom” that has an upside: finally prioritizing yourself and your needs.
Final thoughts…
Perimenopause is messy, confusing, and often isolating, partly because we still don’t talk about it enough. If you’re reading this and recognizing yourself in multiple symptoms, know that you’re not losing your mind and you’re definitely not alone. These symptoms are real, they’re valid, and they’re incredibly common.
While some symptoms may require medical intervention (especially heavy bleeding or severe mood changes—please talk to your doctor), simply knowing what’s happening can provide relief. You’re not broken; your body is transitioning. And importantly, you don’t have to suffer through this silently. Whether through medical support, lifestyle changes, or simply connecting with others going through the same thing, there are ways to navigate this challenging phase.
