Period mood swings vs Perimenopause mood swings

Let’s be honest — of all the symptoms that come with perimenopause, mood swings and anxiety can be some of the trickiest to navigate. Physical symptoms we often just get on with. But emotionally? It can feel like you’re losing your grip a bit.

The thing is, most of us are already familiar with hormonal mood shifts. Over the years, we’ve learned how to handle the emotional ups and downs of our monthly cycle. We’ve become seasoned surfers, riding the hormonal waves with experience and (mostly) grace.

Typically, we know the drill: everything starts to feel a bit off, people get more irritating than usual, and you suddenly feel like crying over nothing. Then it clicks — "Ohhh, my period’s due." That realisation brings a certain relief, because you know it’s temporary. It’ll pass.

But during perimenopause, things can feel quite different.

The Unpredictable Hormone Shift

As oestrogen and progesterone levels begin to fluctuate more erratically, the emotional symptoms that come with them can catch you off guard. You might suddenly feel anxious for no clear reason, or experience a low mood that doesn’t seem to be connected to anything in particular — including your period.

And because these moods don’t always follow the familiar monthly pattern, they can feel unpredictable and unsettling. One minute you’re fine, the next you’re teary, snappy, or just deeply flat — and you’re not even sure why.

So, What Can Help?

The good news is: you don’t have to just grin and bear it. There are simple, supportive steps you can take to help manage the emotional side of perimenopause.

For some women, gentle herbal support can make a difference. Products like Focus Perimenopause Passiflora Complex may offer a bit of extra support.

But don’t underestimate the basics. Supporting your nervous system is crucial. Here are a few simple things to consider trying:

  • Learn deep breathing techniques and practice them throughout the day
  • Go for a calming walk
  • Go to bed a bit earlier
  • Make sure you’re not skipping meals

It might sound too simple, but these little acts of self-care really can have a cumulative effect on your emotional wellbeing. Personally, I always notice my mood worsens when I’m running on empty — whether that’s due to poor sleep, not eating properly, or low iron levels (which are surprisingly common during perimenopause, especially if you're having heavier periods).

Start Tracking (Even If It’s Irregular)

Even if your cycle feels all over the place, tracking your symptoms can be really powerful. You might start to spot patterns — emotional, physical, or both — and that insight can be incredibly helpful. Not only for your own understanding, but also if you decide to speak with your GP or seek support from a holistic practitioner.

You’re Not Alone

Perimenopause can feel like an emotional rollercoaster at times, but the important thing to remember is: you’re not alone in this. With awareness, support, and the right tools, those waves of emotion can become a little less overwhelming — and a lot more manageable.
