PMS in a Relationship: What Partners Should Know – and How to Talk About It

Irritable, exhausted, thin-skinned – and nobody quite knows why it's happening right now? The days before a period can be hard on both of you. With a bit of knowledge and a shared language, it doesn't have to become a source of conflict – it can become something you carry together.

What PMS actually is

Premenstrual syndrome, or PMS for short, covers symptoms that regularly come back before a period. According to the Austrian health portal, they usually begin a few days to two weeks before bleeding and fade again when it starts – or one to two days afterwards.

The list of possible signs is long: breast tenderness, abdominal pain or headaches, water retention, tiredness, sleep problems, but also irritability, low mood, insecurity or difficulty concentrating. Many women only have mild symptoms now and then. According to gesund.bund.de, around 20 to 40 percent experience several, more pronounced PMS symptoms.

Important for both of you: PMS isn't the same every month. Some cycles go by almost without symptoms, others are noticeably harder.

Why PMS affects the relationship too

When patience is shorter and energy is low, the person closest usually notices too. gesund.bund.de explicitly points out that PMS can put a strain on relationships with family, friends and partners. At the same time, the portal describes a worry many women know well: being written off as “hormonal” and not taken seriously.

That's exactly the crux. A partner who blames every bad day on “that time of the month” hurts. A partner who knows nothing about it is confused. In between lies something better: understanding that doesn't patronise.

What partners should know

• It's real. The symptoms are not a mood and not an act.
• It's not aimed at you. Irritability can hit you without you being the reason.
• Feelings are still valid. If she's annoyed about something, the annoyance isn't automatically “just PMS”. Sometimes PMS days are simply the days when something left unsaid comes to the surface.
• She knows herself best. She knows what's good for her – or will find out. Your job isn't to know better, but to ask.
• Every month is different. What helped last time may be too much this time.

How to talk about it – without blame

The most important conversation about PMS doesn't happen on a PMS day. Pick a calm moment when you're both doing well, and talk about what the days before her period are like for you.

• Ask instead of interpreting: “How do you feel in the days before your period?” opens up more than “You're always so… then”.
• Use “I” statements: “I notice I'm unsure how I can help you then” instead of “There's no talking to you then”.
• Agree on a signal: a word or emoji that says “I need some peace today” – without a long explanation.
• Never use PMS as an argument: “You're only saying that because of your period” ends any conversation. If a topic matters, it's better to move it to a better day.

Small gestures that make a big difference

Support doesn't have to be big. Often it's the little things: rescheduling an appointment, taking care of dinner, getting the hot-water bottle ready, suggesting a quiet evening instead of a packed schedule – or simply giving her space. gesund.bund.de mentions, for example, shifting down a gear during this time and consciously making room for relaxation, such as a walk or a cosy evening.

Which gesture lands well is very personal, though. One person loves closeness, another mostly needs peace and quiet. You can read more about how to find out together what really helps in our article What helps with PMS?.

Looking ahead instead of being caught off guard

A lot of tension arises because PMS days “suddenly” appear. Yet for many women they follow a pattern. Health portals recommend recording symptoms for two to three months in a kind of diary – that way you can see when they occur and how strong they are.

If you both know that quieter days are coming up in a few days, you can plan your calendar around them: perhaps not the exhausting family party right then, and the short break rather the week after. We explain how the individual phases fit together in The cycle phases explained simply.

When medical advice makes sense

If symptoms seriously affect everyday life, work or the relationship, it's worth seeing a gynaecologist. There is a severe form, premenstrual dysphoric disorder (PMDD), in which mental health in particular is heavily affected; according to gesund.bund.de, it affects roughly 3 to 8 percent of girls and women. A symptom diary helps when talking to the doctor.

And very importantly: if dark thoughts come up, or thoughts of harming yourself, get help right away – in Austria, for example, from the Telefonseelsorge crisis line on 142, in Germany on 0800 111 0 111, and in an emergency via 144 or 112.
