Why Am I So Unmotivated A Week Before My Period?

WHAT THE HELL HAPPENED?

A few days ago, I had some serious plans to get some shit done.

Like, actual plans. I woke up excited about working on my website. I had accounting shit I could work on. I had a list, and I had good intentions.

And for the first part of the morning, I did okay. I knocked out a few administrative things. I was moving along.

Then sometime around the afternoon, I just . . .

Didn't fucking feel like doing any of it anymore.

Not exactly tired. Not incapable of working. I just didn't want to. The things I had been excited about that morning suddenly felt harder. Making decisions felt harder. Moving something forward felt harder.

And I had this feeling that if I forced myself to work on it anyway, I wasn't going to be giving it my best.

And you know where my brain immediately wanted to go:

Why are you being so lazy?

Why are you procrastinating?

Why can't you just get your shit done?

You know. All those incredibly supportive things we say to ourselves.

Except this time, I did something different.

I looked at my tracker.

I was on Day 20 of my cycle, so I pulled out the tracker I've been using and started flipping backward through my notes.

And there it was.

“Tired and unmotivated.”

Two months earlier. Day 20. The exact same day of my cycle.

And that changed the conversation immediately.

Maybe I wasn't suddenly lazy. Maybe I wasn't failing at discipline.

Maybe there was a pattern here.

HORMONAL HELL

So, can your cycle actually fuck with your motivation?

Turns out, maybe.

After ovulation, you enter the luteal phase of your menstrual cycle. Estrogen and progesterone continue changing throughout this phase, and if pregnancy doesn't occur, both eventually fall as you approach your period.

Those hormonal shifts don't just affect your period. Estrogen and progesterone also interact with your brain, which means changes across your cycle can potentially affect things like mood, cognition, reward and motivation.

And there is some fascinating research here.

A 2026 study followed naturally cycling women across their cycles and measured several aspects of motivation. The researchers found that motivation decreased during the periovulatory and luteal phases in their sample.

So yes: the hormonal changes happening across your cycle may be part of why your motivation feels different at different times of the month.

But it's not as simple as saying, My estrogen dropped, therefore I don't want to work today. Researchers are still trying to understand exactly how individual hormones, their fluctuations, their interactions with each other, and everything else happening in the body contribute to those changes.

Which is annoying, because sometimes I really would like something specific to blame.

GOOD OLE PERIMENOPAUSE

This is where things can get even harder to predict.

Estrogen and progesterone don't necessarily follow those nice, predictable curves you see on menstrual-cycle charts. Ovulation can become less consistent. Hormone levels can fluctuate more dramatically. And the timing and intensity of symptoms can change from one cycle to another.

A 2026 systematic review of 26 studies involving more than 9,000 women found differences in cognitive functioning between women in perimenopause and women who hadn't entered perimenopause yet.

Another study found that greater estradiol variability was associated with more depressive symptoms in the perimenopausal women they studied.

None of that proves that hormones caused my Day 20 motivation crash.

But it gives me a pretty damn good reason to pay attention to the pattern.

DAY 20 IS NOT OFFICIALLY "NO MOTIVATION" DAY

Please don't read this and immediately circle Day 20 on your calendar with:

CRYSTAL SAYS I WILL BECOME USELESS TODAY.

That's not what I'm saying. 😂

What got my attention wasn't that Day 20 is somehow universally significant.

It was that I had written the exact same thing on the exact same cycle day two months earlier.

That doesn't prove hormones caused it. It doesn't mean it's going to happen on Day 20 every month. And it definitely doesn't mean you'll experience the same thing.

But seeing “tired and unmotivated” sitting there in my own notes from two months earlier?

That made me curious.

And I think that's the point.

I JUST STOPPED

Once I saw the pattern, I made a decision.

If something genuinely had to happen that day, I'd do it.

But if it didn't?

I wasn't fucking doing it.

And I wasn't going to spend the rest of the day feeling guilty about it.

Obviously, we can't always rearrange our lives around how we feel. Kids still need things. Jobs still have deadlines. Dogs still need to be fed. Sometimes you have responsibilities, and you have to get shit done whether your hormones approve or not.

But I'm also realizing how many things on my to-do list I arbitrarily label URGENT when absolutely nothing terrible would happen if I did them tomorrow.

Maybe my brain was asking for a break.

Maybe I could listen instead of immediately deciding there was something wrong with me. And then something funny happened.

I stopped trying to make myself work on the website - and suddenly I wanted to work on my newsletter. Then I started thinking about this article and got excited again.

So apparently I wasn't incapable of doing anything that day. I just didn't have motivation for the thing I was trying to force myself to do.

And I think that's worth paying attention to, too.

Maybe “I'm unmotivated” doesn't always mean “I have no motivation.”

Maybe sometimes it's information.

That's what tracking my cycle is starting to teach me.

Not that every emotion is hormonal.

Not that every symptom can be explained by what day of my cycle I'm on.

And definitely not that there's a perfect schedule we're all supposed to follow.

It's teaching me to stop assuming that every uncomfortable feeling is evidence of some personal failure.

Notice what's happening.

Look for patterns.

Get curious before you start blaming yourself.

Because sometimes there's something you can change.

Sometimes there's something else going on that's worth investigating.

And sometimes?

It's just your fucking hormones.
