PMS, PMDD and your relationships: what helps
The week before a period can strain friendships, relationships and shared rooms. What new research shows, and four things that help, for you and the people around you.
If you have ever snapped at a roommate, gone quiet on a partner or skipped a chamber meeting in the week before your period, then wondered afterwards why everything felt so much louder, you are not imagining it. Premenstrual changes affect more than the body. They change how you think, how you communicate and how close you feel to the people around you.
This piece is for anyone who gets a period, and just as much for the friends, partners, roommates and coursemates who share their lives.
What is actually happening
The one to two weeks before a period is called the luteal phase. Hormone levels shift during it, and the brain's mood systems respond. For many people that shows up as irritability, tearfulness, anxiety, low energy or feeling easily overwhelmed. That is premenstrual syndrome, or PMS, and it is common.
For a smaller group, the change is severe enough to disrupt work, study and relationships every month. That is premenstrual dysphoric disorder, or PMDD. Researchers at Durham University estimate it affects about 2 in every 100 people who menstruate. Its symptoms can include brain fog, cramps, bloating, mood swings, anger, sadness, low self-worth, anxiety and sometimes thoughts of suicide. People living with it often describe briefly not feeling like themselves at all.
The key point: this is a physical change in the brain, not a flaw in your personality. You are not "too sensitive" or "dramatic". Something real is happening. The symptoms usually ease once the period starts, but the knock-on effects, such as missed classes, a strained friendship or an argument left unresolved, can last longer. That is why planning ahead matters.
Why relationships take the hit
In 2025, Durham University psychologist Dr Sophie Hodgetts published the first research into how PMDD affects life at home, looking at both people with PMDD and their partners. Compared with people without the condition:
- People with PMDD reported lower quality of life in every area studied: physical health, psychological health, social relationships and living conditions. Several of these stayed lower *whatever the point in their cycle*, not just in the hard weeks.
- Their relationships scored lower on trust, intimacy and passion. But love and commitment were just as strong as in other couples. The care is still there; it is the day-to-day closeness that takes the strain.
- Partners were affected too. They reported lower quality of life and the same pattern in their relationship: lower satisfaction with trust, intimacy and passion, with love and commitment intact. Many end up in something like a carer's role, and research on other mood conditions shows carers need support of their own.
The researchers' conclusion is that support has to go beyond medication and managing symptoms, and has to include the people closest to the person with PMDD.
PMS is milder, but research on couples points the same way. Partners struggle most when they do not understand what is happening, and when partners understand what PMS is, things get better. Knowing what is going on is one of the most useful things you can do.
Why it matters on campus
Student life puts a lot of pressure into a small space: shared rooms, group projects, chamber executives working closely together, relationships that run alongside exams. Your cycle does not check the timetable. A test or a moot can land in your hardest week. Knowing that ahead of time is not making excuses. It is planning.
Four things that help
1. Track your pattern. For two or three months, note your mood, energy and how you are getting on with people each day, alongside your cycle. A notes app or a calendar is enough. You are looking for the days that are reliably harder. Once you can see them, you can plan for them instead of being caught out each month.
2. Make a plan before the hard week. Talk to a partner, close friend or roommate when you are feeling fine, not in the middle of it. What helps? More space or more reassurance? Fewer plans? A code word that means "I'm overwhelmed, it's not about you"? Agreed in advance, it saves a lot of misread moments later.
3. Name it without blame. Something like: "I'm in the rough part of my cycle. Everything feels louder, but I still care about you. I need a bit of space." It tells the other person what is happening without making them the problem, and it usually stops an argument before it starts.
4. Plan your study around it. If your tracking shows a hard week, use the ChamberOS Planner to put lighter tasks there and heavier revision either side. If a test falls in that week, start preparing earlier.
If you are the friend, partner or roommate
- Don't dismiss it. "Is it that time of the month?" said as a put-down makes things worse. Asking "is this a rough week? What would help?" makes them better.
- Don't take every sharp moment personally, and don't treat real concerns as "just hormones" either. Both can be true at once.
- Ask what helps, then do it. Space, food, a quiet evening or company: the answer differs from person to person, so ask.
- Look after yourself too. The Durham research found partners' wellbeing suffers as well. Supporting someone does not mean carrying it alone. Talk to a friend you trust, and keep doing the things that keep you steady.
When to get help
If premenstrual symptoms regularly stop you studying, working or functioning, cause serious conflict, or bring thoughts of self-harm, talk to a doctor. PMDD is a recognised medical condition and there are treatments that work. Bring your symptom tracking to the appointment. Doctors diagnose PMDD from daily symptom records kept over at least two cycles, so your notes are exactly what they need.
Your university health centre is a good first stop. At OAU, the Campus Health page in ChamberOS has the health centre's details and opening hours. If you are ever in crisis or thinking about harming yourself, contact emergency services or someone you trust right away.
