What If It Isn’t Postpartum Depression?

Take a breath, love. These early days can be tender, exhausting, and full of unexpected emotions. Whatever you’re feeling—heavy, numb, anxious, or just unsure—it matters. You may be wondering is this what postpartum depression feels like? Is what I am feeling normal? Or is it something else? Let’s softly unpack what might be going on beneath the surface.

As a doula, I’ve walked alongside many new parents during those raw, beautiful, and overwhelming early months. One thing I’ve learned is this: there are many reasons something can feel “off,” and it doesn’t always fit neatly into the box of postpartum depression. Yes, PPD is real and important to recognize—in fact, nearly one in seven women will suffer from postpartum depression. But, there are many other physical, emotional, and spiritual shifts that can leave you feeling unlike yourself. This article will give you seven possibilities to explore if you’re looking for a potential root cause of the way you are feeling that isn’t just chalking it all up to hormonal shifts.

PS. Before we dive into these topics, if you are looking for a therapist please talk to someone. Most insurance companies cover therapy, even online therapy like Talkspace, with a $0 copay.

You can also get support from the National Maternal Mental Health Hotline at anytime by calling or texting 1-833-TLC-MAMA (1-833-852-6262) for free, confidential support for pregnant and new moms.

7 Reasons Moms Might Feel Off Postpartum

1. Thyroid Dysfunction

The thyroid is a butterfly-shaped gland in your neck that produces hormones regulating metabolism, energy, and overall body function. Up to 23% of all new mothers experiences thyroid dysfunction postpartum. A dysfunctional thyroid can significantly impact a postpartum woman’s physical and emotional well-being. Low thyroid function (hypothyroidism) can cause extreme fatigue, mood changes, brain fog, and difficulty coping—symptoms that can easily be mistaken for postpartum depression. It may also disrupt sleep, milk supply, and overall recovery. Because thyroid issues are common after birth, getting tested can help ensure the right support and treatment.

Testing can be requested by your OB-GYN, Midwife, Dietician, Primary Care Doctor, or Endocrinologist, Results typically come back within a few days. If levels are abnormal, your provider will discuss treatment options, which can include diet, medication and monitoring.

2. Low Iron

Low iron can have a major impact on a postpartum woman’s energy and mood. It often causes extreme fatigue, weakness, dizziness, and shortness of breath. The combination of these symptoms can make daily tasks and caring for a newborn feel overwhelming. Low iron can also contribute to irritability, difficulty concentrating, and feelings of low mood, sometimes mimicking postpartum depression.

Because iron is crucial for red blood cell production and overall energy, addressing a deficiency through diet or supplements can dramatically improve physical and emotional well-being. However, please work with your a qualified medical provider to get the right dosing as too much iron can also be dangerous. Because of this, many prenatal vitamins do not include an iron at all. Not sure if this could be you? Low iron is most often caused by untreated iron deficiency in pregnancy, or blood loss during or after birth. Over time, iron stores will usually recover. However, 20-50% of women enter postpartum with an iron deficiency.

3. Low Vitamin D

Are you getting enough sunlight? I know where I live here in Seattle, it is nearly impossible throughout most of the year. Because we are cloaked in clouds and rain, it’s not surprising that vitamin D deficiency is a common occurrence. This is a problem because low vitamin D can significantly affect a postpartum woman’s mood, energy, and overall well-being. Deficiency is linked to increased fatigue, weakened immunity, muscle aches, and a higher risk of anxiety or depressive symptoms. Because vitamin D helps regulate hormones and supports brain function, low levels can intensify the emotional ups and downs of the postpartum period. Correcting the deficiency—through sunlight, diet, or supplements—often leads to noticeable improvements in mood and vitality.

In one study, over 40% of women had below optimal levels of Vitamin D, and over 20% had more severe deficiencies. You can find out if you have low vitamin D by getting a blood test through your doctor or midwife. Symptoms like fatigue or muscle aches can be clues, but only the blood test can confirm a deficiency. From there, your doctor can help you determine if sunlight or supplementation is needed to correct a deficiency or if you can rule this out as a potential contributor to feeling off.

4. Unresolved Birth Trauma

Up to 45% of new mothers have reported experiencing birth trauma. Unresolved birth trauma can be masked as postpartum depression because many of the emotional and physical reactions to a traumatic birth—such as anxiety, intrusive memories, numbness, irritability, panic, or a sense of disconnection from the baby—can closely resemble postpartum depression or anxiety symptoms. A woman may appear depressed when she is actually experiencing the lingering effects of fear, loss of control, or medical trauma that went unprocessed after delivery. Since these trauma responses often blend with the exhaustion and overwhelm of early motherhood, they may go unnoticed or misinterpreted as typical postpartum depression.

Healing from birth trauma is not something a mother should have to navigate alone. The most effective support often comes from a licensed mental health professional who specializes in perinatal or birth trauma, such as a perinatal therapist, trauma-informed counselor, or psychologist trained in approaches like EMDR, somatic therapy, or CBT. These professionals understand the unique emotional and physical layers involved in traumatic birth experiences and can guide a mother safely through processing what happened. In addition, support from a trauma-informed midwife or OB provider can offer clarity about the medical aspects of her birth, while a postpartum doula can help reduce overwhelm and create practical stability at home. Some mothers also find comfort and validation in birth-trauma support groups, where they can connect with others who’ve experienced similar feelings. Together, this team can help a mother feel seen, supported, and empowered as she moves toward healing.

5. Sleep Deprivation

When I am working with a new family and helping them plan for postpartum, one of the most helpful peices of advice is to plan 12 hours to get 8 hours of sleep. Meaning that if you go to sleep at 10, don’t plan a morning routine until 10 the next morning. Because, you will wake up several times a night to feed a baby, and you need to make it up. It’s essential to your health.

Sleep deprivation can quietly blur into postpartum depression because when you are running on empty, everything feels heavier, harder, and more overwhelming than it truly is. The fog of exhaustion can bring on tears, irritability, anxiety, and difficulty bonding—all symptoms that look and feel like depression, even when the root is simply a desperate need for rest. Over time, that lack of sleep can erode your emotional resilience and tip you into genuine postpartum depression, making it nearly impossible to tell where exhaustion ends and deeper struggles begin.

As a postpartum doula, one of the things I have noticed is that sleep problems are often caused by feeding problems. A baby not gaining weight though feeding constantly, a nurse saying to massage the breasts, feed, pump and then bottle feed every time the baby eats, waking up in the middle of the night and finding all the bottles dirty before preparing formula. All these things may seem small, but can lead to moms missing out on the precious little sleep that is available in the newborn period. If you feel like you aren’t getting enough sleep, check with a lactation consultant on feeding issues and also check in with your partner, support system and postpartum doula to see how you can fit in more sleep and which responsibilities need to be carried by someone else.

6. Identity Shift

Matrescence—the profound physical, emotional, and identity shift that happens as you become a mother—can sometimes feel a lot like postpartum depression in certain moments because becoming a mother involves intense change, vulnerability, and upheaval. As you adjust to your new role, you are going to grow, and with that change can come periods of time of feeling unmoored. No longer who you were, but not yet settled into this new expanded version of yourself. If you are trying to figure out and understand the emotional and physical changes that are happening, I’d recommend adding a couple books to your Kindle for your nap trapped, snuggly skin-to-skin moments.

The first is Mama Rising by Amy Taylor-Kabbaz – a book that explores the transformative journey of matrescence—how becoming a mother reshapes your identity, emotions, relationships, and sense of self. It offers compassionate insights, practical tools, and empowering stories to help mothers navigate this transition with confidence and clarity.

The second is Matrescence: On Pregnancy, Childbirth and Motherhood by Lucy Jones which delves into the psychological, emotional, and physical transformation women experience as they become mothers. The thing that I love about this book is that it is so honest are raw, but also gives so much hope and validation. It truly helps a woman feel connected with the millions of other women who are going through similar beautiful but difficult periods of growth.

7. Isolation Or Unfair Division Of Labor

These could be separate points, but are often linked together. Not only do relationships change after a baby, which can lead to a mother feeling alone, but it’s possible to also be separated from community, friends and those that can relate to your journey and evolution as a mom. If you’re having problems with all the responsibility falling on you instead of on you and your partner, it’s time to rope a couples counselor in. Many families have a harsh adjustment as they realize how much work a baby is.

On top of that, research has highlighted four key experiences that often leave new mothers feeling isolated: a lack of support, being part of a group that society commonly marginalizes—such as immigrants or refugees—a profound sense of lost identity, and the fear of not being a “good enough” mother. These experiences aren’t just emotional challenges; they directly lead to social isolation and can set the stage for postpartum depression. Connection is a crucial human need in the postpartum period.

Here in Seattle, we have wonderful and affordable places to connect with other mothers. Bring the Baby Fitness, the Heybrook, a center for new moms in Kirkland and Wedgewood. If you aren’t local to this area, look for your own mama and baby meetups. Even connecting with one friend on an app like the Peanut App, which is specifically designed to help moms meet moms, can make a difference. I once worked with a mom who moved when her baby was only 3 months old. She told me she used this app to challenge herself to go on ‘fifty first dates’ so to speak to build a village. It only took 7 and she had a new twin to parent, grow and mom with.

So What Is The Truth About Postpartum Depression?

Postpartum depression is a real occurrence and I do not mean to minimize the experience by pointing out the multitude of possibilities that can be confused with postpartum depression or not treated because of a postpartum depression diagnosis.

If what you’re experiencing doesn’t fully feel like postpartum depression, that doesn’t mean your feelings are any less real or valid. Sometimes the intense emotions, exhaustion, or disconnection you’re facing may be rooted in postpartum depletion, birth trauma, matrescence, sleep deprivation, or simply the enormous transition into motherhood. Acknowledging this possibility opens the door to understanding yourself with curiosity and compassion, rather than judgment. Whatever the cause, reaching out for support—whether through therapy, community, or trusted loved ones—can help you navigate these changes, heal, and rediscover joy in your new role. You don’t have to face it alone, and your experience matters exactly as it is.
