## Quick answer

- Anxiety is a common luteal-phase PMS symptom.
- Breathing, regular meals, movement and less caffeine can help.
- Tracking shows whether it is cyclical.
- Persistent or severe anxiety needs professional support, and you can self-refer.

If your brain starts replaying every awkward text you have ever sent in the days before your period, you are not alone. The NHS lists feeling upset, anxious or emotional as common [PMS](https://splash.care/learn/glossary/pms) symptoms. [PMS](https://splash.care/learn/conditions/pms) symptoms are defined as easing within a few days of your period starting.

## What it can feel like

- Racing or looping thoughts ([Rumination](https://splash.care/learn/glossary#rumination))
- Feeling tense, on edge or easily overwhelmed
- Trouble sleeping
- Physical signs like a racing heart or tummy flutters

## Things that help

- A slow breathing [exercise](https://splash.care/learn/period-care/exercise-on-period) for 5 minutes (see our breathing quickies)
- A worry window: the NHS suggests setting a daily "worry time" to go through your concerns, so they have a place to go
- Regular meals. The NHS says to eat a healthy diet with regular meals to keep energy steady
- Easing off coffee, tea, cola and energy drinks. The NHS says [caffeine](https://splash.care/learn/nutrition/caffeine-alcohol) can disrupt [sleep](https://splash.care/learn/movement-sleep/sleep-cycle) and make anxiety harder to control
- Moving your body. The NHS says running, walking, swimming and yoga can reduce anxiety and [stress](https://splash.care/learn/cycle-basics/stress-travel-illness)
- Reminding yourself: "This is my luteal brain talking. It will pass."

> **Splash says:** try a worry window. Give your worries 10 minutes at a set time, write them down, then close the notebook. Anything urgent will still be there tomorrow.

**Quick quiz:** If anxiety reliably appears before your period and lifts once it starts, what is most useful to do?

1. Ignore it
2. Track it daily for two cycles and share the pattern with a GP
3. Assume it will be like this forever

Answer: Track it daily for two cycles and share the pattern with a GP. The NHS suggests keeping a symptom diary for at least 2 cycles. A clear pattern helps a GP tell PMS or PMDD apart from other anxiety, and choose the right support.

### When to see a doctor

See a GP if anxiety is severe, includes panic attacks, lasts beyond your period, or stops you doing everyday things. If you are 18 or over you can also refer yourself to NHS Talking Therapies (some areas take 16 and over). The NHS says feeling anxious most of the time for 6 months or more may be generalised anxiety, which is treatable. If you ever feel unsafe or have thoughts of harming yourself, please reach out now. If you are in danger, call 999 or go to A&E. For urgent help that is not an emergency, call NHS 111 and choose the mental health option (England), or call Samaritans free on 116 123, any time. You can also text SHOUT to 85258.
