If you’re reading this, chances are you’re either newly pregnant, thinking about becoming pregnant, or already experiencing unpredictable emotions. Mood swings during pregnancy are one of the most common pregnancy symptoms, often appearing early in the journey. While it can be confusing or even overwhelming, know this: you're not alone, and what you're feeling is completely normal.
In this blog, we explore when mood swings start in pregnancy, what causes them, and how to manage physical and emotional changes for a healthy pregnancy experience.
When Do Mood Swings Start in Pregnancy?
Spoiler alert: they can kick in almost immediately after conception.
Early Pregnancy: The First Trimester
Mood swings can begin just a few weeks after conception. Many women experience mood swings early on—even before a missed period or a positive pregnancy test. Hormonal changes—especially the sudden rise in estrogen and progesterone—can impact neurotransmitters in the brain, causing sudden emotional shifts. These hormonal changes often coincide with other early pregnancy symptoms like morning sickness, fatigue, and tender breasts.
During the first trimester, pregnant women might notice increased sensitivity, crying spells, or anxiety. These are not just emotional symptoms but signs of how your body prepares for the months ahead. It’s common to feel exhausted during the early stages, and physical and emotional fluctuations can be intense.
Second Trimester: A Period of Stability
By the second trimester (weeks 13–26), hormone levels begin to stabilize. Many women report feeling emotionally balanced during this time. Morning sickness often fades, energy improves, and physical activity becomes more manageable. This trimester is sometimes called the "honeymoon phase" because both physical and emotional changes tend to ease.
Still, life stressors, pregnancy symptoms, or concerns about the baby's health may trigger emotional waves. Managing these with consistent routines and emotional support is essential for maintaining a healthy pregnancy.
Third Trimester: Mood Swings Return
In the third trimester, mood changes may intensify again. As your due date approaches, you may experience heightened physical stresses like back pain, sleep deprivation, or digestive discomfort. Hormonal fluctuations continue as the body prepares for labor.
You might feel anxious about childbirth or parenting, and physical discomfort can add to the emotional load. Sleep becomes harder due to a growing uterus and frequent bathroom trips. These factors can contribute to renewed mood swings during pregnancy.

What Causes Pregnancy Mood Swings?
Hormonal Changes
Estrogen and progesterone levels increase rapidly in early pregnancy. These hormones influence brain function and affect mood regulation. These hormonal changes can cause irritability, sadness, or anxiety—sometimes all in one day. These shifts are entirely normal as your pregnant body adjusts to support the growth of a new baby.
Physical and Emotional Changes
From swollen breasts to an expanding belly, the physical changes of pregnancy can impact your self-image and daily comfort. Emotionally, worries about your identity, partner support, or career may surface. These significant changes can cause mood instability and make many pregnant women feel uncertain.
Stress and Anxiety
Concerns about parenting, finances, or your own health are common. But sustained stress can increase anxiety and lead to emotional lows. Identifying stressors and learning how to manage them—through self-care, mindfulness, and routines—can help prevent these feelings from becoming overwhelming.
Identity Shifts and Relationship Strain
Pregnancy can transform how you relate to yourself and others. You may grieve your pre-pregnancy lifestyle or feel distanced from your partner. These shifts are valid and can contribute to emotional symptoms like moodiness, sadness, or isolation. Talking to a family member, therapist, or peer support group can help you feel seen and supported.
How to Cope With Mood Swings During Pregnancy
Maintain a Healthy Diet
A healthy diet helps stabilize mood and boost energy. Include protein, fiber, and slow-digesting carbs. Eat small, regular meals to prevent drops in blood sugar that can cause irritability. Avoid an empty stomach, which can worsen morning sickness and emotional lows.
Prioritize Sleep and Rest
Getting a good night's sleep helps regulate mood and energy. Use a maternity pillow for support, establish a calming bedtime routine, and avoid screen time before bed. Treat sleep deprivation seriously—your emotional well-being depends on it.
Engage in Regular Physical Activity
Gentle physical activity like prenatal yoga, walking, or swimming can lift your mood and reduce stress. Regular exercise promotes endorphin release and supports better sleep. Always consult your doctor before starting a new routine.
Practice Mindfulness and Relaxation Techniques
Mindfulness practices like journaling, meditation, or breathing techniques (such as deep breathing) can reduce anxiety and help you stay grounded. Apps or guided relaxation techniques are great tools to center yourself during overwhelming moments.
Talk About Your Feelings
Sharing your emotional experiences is healing. Whether it’s your partner, therapist, or a prenatal care provider, speaking up ensures you feel less alone. Open conversations can reduce shame and improve emotional regulation—especially in the first and third trimesters.
Carve Out Time for Self-Care
Self-care is not a luxury; it’s a necessity. Read a book, listen to music, do something creative—or just rest. Taking care of your emotional health helps you feel more in control, even when hormonal changes are unpredictable.
When to Seek Help for Pregnancy Mood Swings
It’s normal to experience mood swings during pregnancy, but if emotional distress lasts for more than two weeks, it might be time to talk to a professional. Look out for:
- Constant sadness or crying
- Loss of interest in daily life
- Feelings of hopelessness
- Persistent anxiety or racing thoughts
- Trouble bonding with your baby
- Suicidal thoughts
These may be signs of perinatal depression or anxiety, both of which are treatable. Early support promotes a healthy pregnancy for both you and your baby.
