If that thought crosses your mind every month before your period, you’re not being dramatic—your hormones might be doing more than just causing cramps and cravings. For many women, the premenstrual phase brings a wave of mood swings, irritability, fatigue, and even sadness. But when those emotional shifts feel extreme or deeply disruptive, it could be more than PMS.
Let’s talk about PMS vs. PMDD—what they are, how to tell the difference, and what you can actually do to feel like yourself again.
PMS, or Premenstrual Syndrome, is the term we often use to describe the physical and emotional symptoms that show up a week or so before your period. For most, it might look like:
While PMS can be annoying (and sometimes intense), it’s usually manageable and doesn’t completely derail your day-to-day life. It’s something up to 75% of women experience during their reproductive years.
Now enter PMDD—Premenstrual Dysphoric Disorder. This is PMS’s more intense, emotionally overwhelming cousin. PMDD is a clinically recognized mood disorder that affects about 3–8% of women, and it’s not just “PMS on steroids.” It’s a serious condition that can deeply impact your mental health, relationships, and overall functioning.
Common PMDD symptoms include:
The symptoms usually disappear a few days after your period starts, but the lead-up can feel like a mental and emotional storm you can’t escape.
Here’s the difference in a nutshell:
If your symptoms consistently interfere with your ability to work, parent, socialize, or simply feel okay, it’s worth looking into PMDD. You’re not “just moody”—your brain is responding to hormone sensitivity.
During the second half of your menstrual cycle (the luteal phase), estrogen and progesterone levels fluctuate. For those with PMDD, these hormonal changes seem to trigger intense emotional responses, likely due to how their brains respond to these shifts.
It's not your fault. It's biology. And it’s real.
If you’ve been struggling in silence, thinking “this is just part of being a woman,” please know: you deserve support, and you’re not alone. Here are some evidence-backed strategies to help manage both PMS and PMDD symptoms.
Awareness is powerful. Use an app or a simple journal to track your symptoms across a few months. This helps identify patterns and gives your healthcare provider a clear picture.
Try: Clue, Flo, or a symptom-tracking notebook.
It sounds basic, but small consistent changes in daily habits can help reduce symptom intensity.
Cognitive Behavioral Therapy (CBT) has been shown to help women with PMS and PMDD reframe negative thoughts and regulate emotions during the luteal phase.
Tip: Practice daily mindfulness meditation or guided journaling to stay grounded when your mood begins to shift.
If lifestyle changes alone aren’t helping, speak to your doctor. Treatment options include:
You don’t need to “push through” every month. Getting medical help is not weakness—it’s smart, proactive care.
This might be the hardest one. When you feel like you’re not in control of your mood or your energy, self-judgment sneaks in. But what if you gave yourself compassion instead of criticism?
You’re not lazy. You’re not “too emotional.” You’re navigating a real condition with strength.
Whether you’re dealing with classic PMS or the more intense waves of PMDD, know this: what you’re feeling is valid. Hormones are powerful, and for some women, they can feel like a complete takeover. But with the right tools, support, and awareness, you can learn to ride the wave—not drown in it.
If this feels familiar, start tracking your symptoms and talk to your doctor. Healing begins with understanding—and you deserve that clarity.
