Is it OCD, postnatal depression, or something more urgent?
Three things can happen in the year after a birth that look alike from the outside and need different responses. Here is how they differ, and which one cannot wait for an appointment.
Something is wrong, and you are not sure what to call it. You have looked things up and found three names, and each fits a little, and the differences seem to matter. They do. One of these is treatable with therapy over some months. One is treatable and often recorded as something else. And one is a medical emergency that should not wait for an appointment with me or anyone like me.
Perinatal OCD
The centre of perinatal OCD is intrusive thoughts, usually about harm coming to the baby, including thoughts of causing it, and the checking or avoiding they drive. The thoughts appal you. You know they make no sense, and that knowledge is precisely why they distress you so much. Your insight is intact; you are not confused about what is real. What has happened is that a thought which most new parents have and forget has stuck, and the day has reorganised itself around making sure: checking breathing, handing over bath time, moving knives, never being alone with the baby.
This can begin in pregnancy or at any point in the first year, and it responds well to CBT with exposure and response prevention.
Postnatal depression
Postnatal depression centres on mood, exhaustion and loss of pleasure. The flatness. The tiredness that broken nights do not explain. Not feeling what everyone said you would feel about the baby. A commentary that has turned cruel: bad mother, fraud, everyone else manages. Small tasks feeling enormous.
It can occur together with OCD, and OCD is often recorded as depression when nobody asks the right question, because a parent who says they are "not coping" gets a mood questionnaire, not a question about intrusive thoughts. If both are present, we treat both. There is more on low mood after a birth on the depression page.
Postpartum psychosis
This is the one that cannot wait. Postpartum psychosis is a medical emergency. It usually comes on fast, in the first days or weeks after birth. The beliefs feel true rather than horrifying; there is no sense that they make no sense. Insight is lost. There may be confusion, elation, racing thoughts, hearing or seeing things, or not sleeping at all, sometimes for days, without feeling tired.
The distinction from OCD is the relationship to the thought. In OCD, the thought about harm is the worst thing you can imagine and you are fighting it. In psychosis, a belief is held as true and acted from. If you are unsure which you are describing, or if anyone around you is worried in this way, contact your GP, midwife, health visitor or NHS 111 today. Do not wait for a therapy appointment. This is treatable, and it is treated urgently, by a different kind of service.
How assessment sorts them
Telling these apart is routine clinical work, not something you need to have worked out before you get in touch. When someone contacts me with a perinatal picture, the first conversation includes it directly: how the thoughts feel, whether they make sense to you, what you do about them, how you are sleeping, how your mood is. If what I hear points to psychosis, I will say so and direct you to urgent care that day. If it points to depression, we treat that, and involve your GP or a perinatal service if needed. If it points to OCD, we treat that. If it is two of them, we treat both.
Working alongside your other care
Where you want it, I am glad to work alongside your GP, health visitor or perinatal mental health team, so the care joins up rather than running in parallel. Sessions run over secure video; you can feed during a session and the baby can be in the room.
Partners too
Fathers and non-birthing partners get perinatal OCD and postnatal depression as well, and disclose it even less often, because every leaflet in the building is addressed to someone else. The treatment is the same, and so is the welcome.
If you have three names and are not sure which is yours, there is more on how I treat perinatal and postnatal OCD, and the sorting is what the first conversation is for.
