Day one landed on a Tuesday, you've got a 9:30 meeting, and not going in isn't an option. Most of us have been there and most of us said nothing. Here's what actually works between 9 and 5, plus the numbers that might make you say something.
The number nobody puts in the HR handbook
A 2019 survey of 32,748 women in the Netherlands, published in BMJ Open, found that 13.8% had missed work or school because of period symptoms. The bigger cost was showing up anyway: 80.7% reported working through symptoms at reduced capacity, an average 33% drop in productivity on those days, which added up to 8.9 days a year. Only 20.1% of those who called in sick told their employer the real reason. And 67.7% said they wished they had more flexibility in tasks and hours during their period. So if you feel like the only person at your desk pretending to be fine, statistically you are not.
10 period hacks for work
1. A heat patch under your shirt. The best hack here, and it has a trial. In a 2001 study, a low-level heat patch worn on the lower abdomen for about 12 hours was as effective as 400 mg of ibuprofen three times a day. Air-activated patches stick to your underwear or waistband, are invisible under clothes, and last a full shift. Buy a box, keep it in the drawer.
2. Take the painkiller before the pain, if you use one. ACOG says NSAIDs work best taken at the first sign of your period or pain, for one or two days, because they reduce the prostaglandins that drive cramps rather than chasing pain that's already there. On the morning you expect day one, that means with breakfast, not at 11 when the cramp has arrived. Check with a pharmacist if you have asthma, stomach problems, or take other medication.
3. The drawer kit. Pads or tampons in two sizes, a heat patch, painkillers, wipes, spare underwear, a black cardigan, a bar of something with magnesium in it. Our period kit checklist has the full list and the under-$40 version.
4. Dress for day one. Dark trousers or a dark skirt, a longer top, the cardigan tied round the waist if needed. You'll probably never need it. The point is that you stop checking, and the attention that frees up is a hack in itself.
5. Walk at lunch. A 2019 Cochrane review of 10 trials found exercise may produce a large reduction in period pain intensity compared with doing nothing, though the evidence is low quality and the trials used 45 to 60 minutes, three times a week. A 20-minute lunch walk is not that. It's still movement, daylight and a break from the chair, and ACOG lists walking among the things that make period pain easier to bear.
6. Stretch at your desk. Seated cat-cow, a gentle twist, feet flat and knees apart with a forward lean. Two minutes, no mat, nobody notices. Our 5-minute stretches for period cramps has the versions that work in a chair.
7. One coffee, not four. A 2024 meta-analysis of 23 studies in female students found high caffeine intake went with roughly twice the odds of period pain. Only two of the studies looked at caffeine, so hold it loosely. The morning cup is fine. The fourth, on day one, on an empty stomach, is asking for it.
8. Block your calendar a month ahead. If your cycle is regular, you know roughly when day one falls. Put a private focus block over the first morning. Move what you can, decline what you can't, keep the meetings that matter. This isn't special treatment. It's what you'd do around a dentist appointment.
9. Water on the desk, lunch away from it. Cleveland Clinic notes dehydration can make cramps worse, and skipping lunch turns the 3 pm slump into a wall. A bottle within reach and a real lunch eaten away from the screen are the least glamorous items here and the ones we skip most.
10. Say something, or don't, but know your options. You don't owe anyone the details. "I'm not well this morning, I'll be on email" is a complete sentence. If you want to go further, the flexibility most women in the survey wanted was small: a later start, working from home on day one, a quiet room. Spain became the first European country to write paid menstrual leave into law in February 2023; most workplaces have nothing like it, but many have flexible-working policies you can use without naming the reason.
A word on the drawer bar. Girl Chocolate is a dark chocolate bar made for the days around your period, with magnesium and other functional ingredients, sold as a pouch of 8 bars so one pouch covers one cycle. It was built for exactly this: a desk drawer, a 3 pm cramp, no fuss. It supports PMS relief* in the small, one-hack-among-ten way everything above does. Here's the bar. The Period Type quiz tells you which days of the month to plan the calendar block around.
The honest limitation
None of this solves a job that punishes sick days, and none of it is a substitute for a doctor if day one regularly puts you on the floor. For years our own approach was to push through and say nothing, which the survey suggests is what four in five of us do. It cost about nine working days a year and we never once got credit for them. The hacks above are what we do now. Item 10 is the one we should have tried first.

When to talk to a doctor
Hacks are for ordinary period days. See a doctor if you have any of these:
- pain that stops you doing daily life, even with painkillers
- bleeding through a pad or tampon every hour
- pain that suddenly got much worse, or changed its pattern
- pain with a fever
