Some people when they hear the words intrusive thoughts automatically assume that the person experiencing said thoughts is hearing voices. Some people think OCD, and others believe intrusive thoughts to be a sign that a person is bad, and will act on their thoughts.
So what are intrusive thoughts?
Intrusive thoughts are unwanted and or distressing thoughts that are often reoccurring. They are likely to leave the thinker very upset, distressed, disgusted, confused and ashamed.
It is thought that 1 in 5 women and mothers will suffer perinatal mood and anxiety disorders, and 57% of those will have experienced intrusive thoughts. Mental health professionals are not entirely sure why more women in the perinatal period experience intrusive thoughts, but it’s believed to be related to a variety of hormonal, environmental, and emotional factors. That said it’s a common symptom of PMADS. Typically, the thoughts that occur in the PP (perinatal period) are fears that surround our children, ‘What if I harm the baby?’ But the thoughts don’t always stop at physical harm and can be of any distressing nature, including sexual fears too.
To be clear before you read on, suffering from intrusive thoughts is NOT a reflection on a person’s character, desires or beliefs. The thoughts themselves go against all of our beliefs and natural instincts as mothers and do not align with our values, hence the very word for them being ‘intrusive.’ We don’t want these thoughts, we can’t bear them and it’s the very reason we are left feeling as though they are ruling and ruining our lives.
During pregnancy with my second child, I became overwhelmed with intrusive thoughts; some of them too abhorrent for me to share —though in some ways, I wish I felt I could share them all, then maybe they wouldn’t have consumed my brain! It got so bad that at just shy of 38 weeks I was hospitalised, under psychiatric care, my labour was induced and I was medicated for my mental health.
After my son was born and I was again assessed by a psychiatrist, she told me thoughts that are violent/harmful or as mentioned, occasionally sexual in nature, are the most common types of intrusive thoughts during the perinatal period. I asked her why this was, and she gave me a fantastic analogy.
You have this tiny human to care for. It’s your most important job, above any other. The thoughts that you are having are in direct conflict with your own anxieties about what could happen to your child. The thoughts are the very things you want less than anything in the world to happen.
But how do you know I’m not just a psychopath? I asked.
‘Because psychopaths don’t phone me up hysterical about upsetting thoughts, you pose absolutely no risk to your children. These thoughts are only hurting you.’
At this stage, I felt so out of my mind I didn’t know if I posed a risk to my children. I felt like I couldn’t think straight. But Dr M was adamant in her statistics in relation to harm caused by intrusive thoughts. Athough it didn’t ease the thoughts initially, it helped me to understand I wasn’t alone and other women and new mothers went through this too. She then went on to say (I feel like this is a big one…) the only person you pose a risk to, is yourself with your judgement about the thoughts.
I found that particular line about judgement really interesting because I realised quite quickly that it WAS the judgement that was keeping me in a cycle of constant fight or flight and inciting suicidal ideation. I felt as though my family would be better off without me.
I was overthinking every single thought and if I dared speak out about my thoughts, rather than feel better, I’d worry about other people’s judgement instead. That was until I met the most wonderful community psychiatric nurse. For the purpose of this blog I’m going to refer to him as Neo (He will appreciate the reference.) Neo has changed the way I think about intrusive thoughts, but more importantly, the way I feel toward opening up about them.
Maternal OCD is a mental illness that affects women in the perinatal period and includes intrusive and obsessive thoughts followed by compulsions completed in order to relieve some of the discomfort from the thought.
Ironically for me, my most intrusive thoughts were about convincing myself I had, or was going to develop severe mental illness (the irony isn’t lost on me.) I first believed I was developing psychosis, I was sure I would go on to hear voices telling me to kill or harm my children. This made me feel disassociated often. Despite not actually hearing voices I was convinced they were coming and I would be sat in my bedroom listening for them. I later googled intrusive thoughts which convinced me I was suffering from severe OCD, despite not having any compulsions. Another common thought for me, was passive suicidality, such as thinking I could just walk out in front of a lorry. Or consume all of the insulin in my possession. These thoughts would come to me during calm activities such as crafting or cooking tea.
When I discussed how I was feeling with Neo, he followed the protocol of having me fill out an OCD assessment, and we discovered that yes I was having obsessive and disturbing thoughts, but I didn’t have the compulsions in that were traditional in a person with Obsessive Compulsive Disorder. I’ve since learned not everybody with OCD experiences compulsions.
Looking back I can see the fear of speaking up about the intrusions was what held me back in my recovery and I would then worry that I was constantly reassurance seeking.
The truth was, there was an element to seeking reassurance, but for the most part I was doing what I needed to do, engaging in therapy and opening up in a safe space.
The mind plays tricks on all of us occasionally, and thoughts are the perfect segue into us believing we are not good people and therefore convincing us we’re unworthy of the love and compassion we so desperately NEED to give ourselves, particularly in the early stages postpartum when you wonder if you’re doing anything right.
Once I finally said aloud that one of my biggest fears was I didn’t want to be alone with my baby because I was terrified I would have a psychotic break and harm him whilst he slept. I was only then able to unpack the thought and see it with clarity for what it was, ‘just’ a thought.
If we all talked about our deepest darkest thoughts, we might be less bothered by them, but even today there is so much assumption and stigma attached to thoughts. People believe that if you think something you must feel it. With intrusive thoughts it’s the exact opposite.
The vulnerability of a woman who has just been through childbirth is like no other time in her life, the fear that we feel is immense. I personally (and wrongly) believed if I told the truth about my thoughts in the early stages postpartum, my children would have been taken away and I would have been sectioned.
You don’t have to open up about every thought in order to dismantle their hold on you though, you can put in to practise strategies and use them for all thoughts that cause you distress.
Neo recommended a book for me to read during my recovery and it’s called The Happiness Trap and is written by Australian doctor, Russ Harris.
In the pages of The Happiness Trap, Harris provides tools to defuse yourself from negative thoughts; and the book itself centres very much on acceptance. It took me a while to come round to the idea that I would ever accept distressing thoughts, but the idea is not to engage with them, just to accept them for what they are, random mental events and words.

If you’re suffering from intrusive thoughts in the perinatal period I would urge you to talk to your doctor. I know it’s hard, you may be feeling judged and terrified, but I promise you the road to recovery starts when you learn that you are not alone with in how you feel.
Organisations that can provide support during the perinatal period are:
- apni.org
- pandasfoundation.org.uk
- maternalmentalhealthalliance.org
- maternalocd.org
- www.birthtraumaassociation.org.uk
I won’t say I’m cured, because that would be a lie, but I’m working towards how to better manage intrusive thoughts and not allow them to take over my life.
