Ever had a week where you felt really anxious and worried about what people were thinking of you? Maybe you felt like you couldn’t control your anger or felt like you could burst into tears every second. Then you get your period and feel much calmer! Well, hormone fluctuations through the month, especially right before your period, could be causing this.

Periods affect mood. Most of us experience mood changes or periods where we feel really anxious and stressed, then calm right before our period starts. This is normal – hormone fluctuations through the month can cause these feelings! So what causes this?

Oestrogen & Progesterone

First, oestrogen and progesterone are hormones that help control the menstrual cycle. They peak before ovulation (when you release an egg) and fall just before your period starts. These fluctuations can cause anxiety or stress because they affect neurotransmitters such as dopamine, serotonin and norepinephrine – all of which regulate mood!

Too much oestrogen can cause high levels of dopamine, which causes more anxiety. Too little progesterone and you might feel like crying all the time!

PCOS & Mood

Another thing to note is that women with PCOS (polycystic ovarian syndrome) tend to have higher testosterone than normal – this also contributes to increased feelings of anger or aggression during your period.

There are also factors that can cause periods to affect mental health, such as childhood trauma or neglect. This may not be related directly to hormones, but early life experiences can really impact how we cope with stress and anxiety later in our lives! If you’re having a tough time dealing with your emotions around your period (or any other time of the month), mental health professionals such as therapists, counsellors and psychiatrists can help.

Your Mental Health

Mental health is just that – it’s a part of your overall well-being and needs to be taken care of! If you’re having issues with anxiety or depression – talk to someone about it sooner rather than later. And don’t be afraid to talk about your cycle – a lot of women experience mood changes around their period and it’s nothing to be ashamed of! If you’re really struggling, try some self-care and take care of yourself. Get a massage or go for a walk – anything to help you relax!


Periods can affect mood in many different ways. They will have an impact on neurotransmitters such as dopamine, serotonin or norepinephrine which all regulate your mood. Oestrogen & progesterone are the main hormones that fluctuate through the month but other factors like childhood trauma may also contribute to mental health issues around periods too so speak with someone about it sooner rather than later if needed!
