Pregnancy can bring a heaviness that does not lift, a tearfulness that arrives without warning, or a flatness that makes it hard to feel interested in things that used to matter to you. These are not the feelings you expected, and they sit apart from the ordinary emotional ups and downs of pregnancy. They are worth paying attention to. Low mood and depression in pregnancy turn up more often than people assume. Perinatal mental health problems affect up to 27% of new and expectant mothers during pregnancy or in the first year after birth.5
The difference between ordinary mood changes and persistent low mood
Feeling tired, irritable, or pulled in different directions is part of pregnancy for most people. Hormonal shifts, physical discomfort, and the size of the change ahead can all move how you feel from one day to the next. These ups and downs come with the territory.6
Antenatal depression, low mood during pregnancy, feels different. It brings a sadness or hopelessness that sticks around, and a loss of interest in things you used to enjoy, lasting weeks or months rather than days. If the low feeling does not ease, or it keeps coming back, that pattern is worth talking through with a professional rather than waiting for it to pass.7
Recognising the symptoms of low mood and depression in pregnancy
It does not always look like sadness on its own. You might notice several of these:
- Persistent sadness or tearfulness
- Irritability or a short fuse that feels out of proportion
- Loss of interest in things you would normally enjoy
- Feeling disconnected from your baby or from the pregnancy
- Poor concentration or trouble making decisions
- Changes in appetite or sleep beyond the usual disruptions of pregnancy18
Noticing these in yourself is not the same as a diagnosis. A midwife or GP can talk through what you are going through and assess it properly.
What can contribute to low mood during pregnancy
Low mood in pregnancy usually comes from several things at once. The nausea, fatigue, and broken sleep that come with pregnancy can wear on your mood, and hormonal changes add to that. These are physical shifts happening in your body.2
What is going on around you and in your past matters too. A history of mental health difficulties, changes in your relationships, little support around you, stressful events, or past trauma can all make low mood more likely during pregnancy. If any of these sound like you, it helps to mention them to your midwife early on, so support can be put in place.3
Practical steps that can support your mood

If your symptoms are mild, a few self-help approaches can help steady your mood alongside professional support. They do not replace proper care when symptoms are persistent or severe. They can still be a useful part of the picture.
- Gentle movement, which can lift your mood without straining your body
- Eating regularly and keeping meals balanced where you can
- Resting when you can, rather than pushing through exhaustion
- Making time for things you enjoy, even small ones
- Connecting with other expectant parents, through antenatal classes or local groups
- Trying relaxation techniques such as mindfulness or breathing exercises9
Talking about how you feel can help too. A partner, friend, or family member is one place to start. If that feels hard, your midwife or GP is there to listen.10
When and how to seek professional support
If the low feeling has stuck around for more than two weeks, it is worth speaking to your GP or midwife. It is worth knowing that clinicians have safeguarding duties, which in limited cases mean some information may need to be passed to other professionals involved in your care.411
Support can include talking therapies such as Cognitive Behavioural Therapy (CBT), a structured talking therapy that looks at how your thoughts and behaviour shape your mood. In some cases, certain antidepressants may be considered during pregnancy. That always comes with a detailed talk through the benefits and risks with your clinical team, and the decision rests with you and your doctor. For more complex situations, you can be referred to a specialist perinatal mental health team.12
