PMS: The Not-So-Calm Before the Storm
If you’ve ever felt like a completely different person in the days before your period — more irritable, more emotional, more tired, more everything — you’re not imagining it.
For some people, it’s subtle. For others, it’s impossible to ignore. Either way, there’s often a pattern: things feel manageable…until suddenly they don’t.
That shift - the build-up before your period - is what we call PMS.
What PMS Actually Is
PMS (premenstrual syndrome) refers to the physical, emotional, and cognitive changes that happen in the days leading up to your period. These symptoms typically show up during the second half of your cycle - after ovulation - and improve once your period starts. For some, though, this timeline doesn’t follow a perfectly predictable pattern, especially if your cycles are irregular or variable.
At its core, PMS is driven by hormonal changes. Estrogen and progesterone rise and fall throughout your cycle, and in the days before your period, those hormone levels drop. That shift affects not just your reproductive system, but also your brain, your mood, your energy levels, and your body overall.
What PMS Isn’t
For a long time, PMS was dismissed. People were labeled as “hormonal,” “irrational,” or worse - and those labels stuck.
That kind of language isn’t helpful, and it’s part of why a lot of people still feel like they have to downplay what they’re experiencing.
The symptoms of PMS are real. The changes in mood, energy, and physical comfort are real. There’s a biological explanation behind them - even if we don’t fully understand why some people feel it more intensely than others.
The goal isn’t to brush it off or blame it on personality. It’s to understand what’s happening and figure out how to make it more manageable.
What It Can Feel Like
PMS doesn’t look the same for everyone, but there are some common patterns.
Some people notice more emotional symptoms: irritability, mood swings, anxiety, or feeling lower than usual. Others notice more physical symptoms: bloating, breast tenderness, fatigue, headaches, or changes in appetite. There can also be a mental component: brain fog, low motivation, or just feeling off.
For a lot of people, it’s not just one thing, it’s a mix. And once you start noticing the pattern, it becomes easier to recognize when it’s happening.
Why It Happens
The exact reason PMS affects people differently isn’t fully understood, but it’s not just about having hormones - it’s about how they fluctuate and how your body responds to those changes.
Many people come in asking to “check their hormones,” thinking something must be off. The truth is, these tests are almost always normal. The range of what’s considered normal is wide, and in normal physiology, these hormones are supposed to rise and fall.
Most symptoms aren’t caused by the absolute value of a hormone - they’re caused by the change. The shift.
As estrogen and progesterone rise and then fall before your period, they influence neurotransmitters in the brain - especially serotonin, which plays a major role in mood, sleep, and emotional regulation.
Some people are simply more sensitive to these changes. That sensitivity can show up as mood symptoms, physical symptoms, or both.
So it’s not that something is “wrong,” it’s that your body is reacting to a very real hormonal transition.
The Luteal Phase
The luteal phase is the second half of your cycle — the time between ovulation and the start of your period. This is when PMS symptoms tend to show up.
During this phase, progesterone rises after ovulation and then drops if pregnancy doesn’t occur. Estrogen also fluctuates and ultimately declines before your period begins.
It’s this hormonal shift - especially the rise in progesterone, which tends to be the moodier hormone, along with the drop before your period - that drives many of the symptoms associated with PMS. For people who are more sensitive to these changes, the luteal phase can feel like a noticeable shift in mood, energy, and overall well-being.
When It’s More Than PMS
For some people, symptoms go beyond typical PMS and start to significantly affect daily life. This is where conditions like PMDD (premenstrual dysphoric disorder) come in.
PMDD is a more severe form of premenstrual symptoms that can include intense mood changes, depression, anxiety, or difficulty functioning in relationships or at work. In some cases, symptoms can become severe enough that people experience suicidal thoughts or even changes in their perception of reality.
This is not normal, and it should never be brushed off.
If what you’re experiencing feels overwhelming or out of proportion to what your peers experience, it’s worth getting evaluated. There are treatments that can help, and you don’t have to just push through it.
What Actually Helps
What helps with PMS depends on what symptoms you’re dealing with, how severe they are, and your personal preferences. There isn’t a one-size-fits-all approach, and for many people, it’s a combination of strategies.
Medical Management
For more significant symptoms, medical treatment can be very effective. It usually breaks down into a few categories.
Hormonal options
This may seem counterintuitive — if hormones are causing the problem, why would adding more help? But like we mentioned earlier, it’s not the hormones themselves — it’s the fluctuations.
Hormonal birth control (like pills, patches, or rings) provides a steady, consistent dose of hormones, which prevents the natural rise and fall that occurs with ovulation. By suppressing that cycle, many people experience fewer symptoms.
That said, hormonal options aren’t perfect. They can come with side effects — sometimes even the same symptoms you’re trying to treat, like mood changes. It often takes some trial and error to find the right type, dose, or formulation that works best for your body.
Mood-focused medications (SSRIs/SNRIs)
In some cases, medications like SSRIs or SNRIs are used — not because PMS is “in your head,” but because of how closely mood symptoms are tied to neurotransmitter changes during this time.
Some people take these medications only during the luteal phase when symptoms occur, but more commonly they are taken daily, since they tend to work better over time.
Like any medication, they come with potential side effects. The most common concerns people report are changes in libido or effects on mental clarity.
Some women’s health providers prescribe these medications, but for more complex cases, it can be helpful to work with a psychiatric or mental health provider as well.
Hormone suppression / advanced options
In more severe cases — particularly with PMDD — more aggressive options may be considered, including medications that suppress ovarian function (such as GnRH analogs).
These medications essentially pause ovarian hormone production. They’re not typically used long-term, but they can help stabilize symptoms in more severe cases while a longer-term plan is developed.
In very rare circumstances, if no other treatment works, surgical removal of the ovaries may be considered. This is not common and is reserved for extreme cases.
While this may sound intense, severe symptoms like suicidal thoughts or psychotic symptoms can be dangerous and life-disrupting. In those situations, it’s appropriate to use every tool available to help.
These are not first-line options, but they exist for people who truly need them.
Non-Prescription and Lifestyle Support
There are also ways to support your body through these changes, especially for mild to moderate symptoms.
Things like sleep, nutrition, and movement can make a difference - not in a “just try harder” way, but in a way that supports how your body is already trying to adjust.
Some people also find benefit from targeted supplements that support multiple pathways involved in PMS - including mood regulation, inflammation, and hormonal shifts.
Ingredients like magnesium, vitamin B6, saffron, ginger, and chasteberry have been studied and have real clinical data supporting their potential to help with both the physical and emotional symptoms of PMS.
These options are often best suited for people with mild to moderate symptoms or for those who prefer to avoid prescription medications.
The goal isn’t to override your cycle, but to support your body as it moves through it.
The Bottom Line
PMS is common, but that doesn’t mean it’s something you just have to tolerate.
If you feel different before your period - emotionally, physically, or both - there’s a reason for it. And more importantly, there are ways to make it better.
You’re not overreacting. You’re not imagining it. You’re just dealing with a part of your cycle that deserves a little more understanding, and a better plan.
