Pregnancy Fatigue: Causes and How to Cope
Pregnancy fatigue can feel different from ordinary tiredness. You may sleep all night and still wake up exhausted. You may feel drained after simple tasks, need naps during the day, or wonder why your energy disappeared so quickly.
If you are experiencing pregnancy fatigue, you are not alone. Feeling very tired is common, especially during early pregnancy and again in the third trimester. Mayo Clinic notes that fatigue is common in early pregnancy as progesterone levels rise, and ACOG says it is common to feel very tired during early and late pregnancy. Source
This guide explains pregnancy fatigue causes, how tiredness can change by trimester, practical ways to cope, and when to call your healthcare provider.
Important: This article is for general education only and is not medical advice. Always follow the guidance of your OB-GYN, midwife, or healthcare provider.
What Is Pregnancy Fatigue?
Pregnancy fatigue is a deep sense of tiredness or low energy during pregnancy. It can feel physical, emotional, or both.
You may notice:
- Needing more sleep than usual
- Feeling tired even after resting
- Low motivation for normal tasks
- Afternoon energy crashes
- Difficulty concentrating
- Feeling emotionally worn down
Pregnancy fatigue can be normal, but extreme or sudden tiredness should be discussed with your provider.
What Causes Pregnancy Fatigue?
Several changes can contribute to fatigue during pregnancy. In early pregnancy, Mayo Clinic explains that rising progesterone may contribute to sleepiness. Your body is also increasing blood volume, supporting the placenta, and adjusting to major hormonal changes. Source
Common causes may include:
- Hormonal changes
- Rising progesterone
- Increased blood volume
- Nausea or vomiting
- Frequent urination disrupting sleep
- Emotional stress or anxiety
- Back pain, heartburn, or discomfort later in pregnancy
- Iron deficiency anemia or other medical causes
First Trimester Fatigue
First trimester fatigue can feel intense. You may feel tired before you even look pregnant. This is because your body is working hard behind the scenes.
During the first trimester, fatigue may be related to:
- Rapid hormonal changes
- Nausea and food aversions
- Lower energy intake if eating is difficult
- Frequent urination at night
- Emotional adjustment to pregnancy
If you are newly pregnant, this is a beautiful time to begin recording how you feel, what you are experiencing, and the questions you want to ask your provider. The Momentiqa Pregnancy Journal Book gives you a gentle place to document symptoms, early thoughts, and first milestones. Explore it here.
Second Trimester Fatigue
Many moms feel more energy in the second trimester, but not everyone does. If fatigue continues, it may be related to sleep disruption, stress, nutrition, anemia, or your body’s individual pregnancy experience.
Talk with your provider if tiredness feels extreme, does not improve with rest, or comes with dizziness, shortness of breath, fast heartbeat, weakness, or feeling faint.
Third Trimester Fatigue
Fatigue can return in the third trimester as your baby grows and your body prepares for birth. Sleep may become harder because of heartburn, back pain, frequent urination, baby movement, or discomfort finding a good position.
Third trimester fatigue may be connected to:
- Interrupted sleep
- Carrying more weight
- Back or hip discomfort
- Heartburn
- Frequent bathroom trips
- Braxton Hicks contractions
- Anxiety about labor or parenting

Could Pregnancy Fatigue Be Anemia?
Sometimes overwhelming fatigue may be related to iron deficiency anemia. Mayo Clinic notes that feeling very tired may be a symptom of iron deficiency anemia during pregnancy, and iron-rich foods or supplements may be recommended if your provider diagnoses anemia. Source
Possible signs to discuss with your provider include:
- Extreme tiredness
- Weakness
- Dizziness
- Shortness of breath
- Fast heartbeat
- Pale skin
Do not start iron supplements unless your healthcare provider recommends them, because too much iron can cause side effects and may not be right for everyone.
How to Cope With Pregnancy Fatigue
1. Rest Without Guilt
Pregnancy is not the time to prove how much you can push through. If your body is asking for rest, listen when you can.
- Take short naps
- Go to bed earlier
- Reduce unnecessary tasks
- Ask for help with chores
- Let rest be part of prenatal care
2. Eat Small, Nourishing Meals
Fatigue may feel worse when your blood sugar dips or when nausea makes eating difficult. Small meals or snacks throughout the day may help some moms feel steadier.
Simple options may include:
- Greek yogurt
- Eggs
- Oatmeal
- Fruit with nut butter
- Cheese and crackers
- Soup
- Smoothies
Ask your provider if you have specific nutrition concerns, diabetes risk, severe nausea, or trouble keeping food down.
3. Stay Hydrated
Dehydration can make fatigue, headaches, and dizziness worse. Keep water nearby and sip throughout the day.
Try keeping water near:
- Your bed
- Your desk
- Your car
- Your couch
- Your pregnancy journal or planner
4. Move Gently If Approved
It may sound surprising, but gentle movement can help energy for some pregnant women. Mayo Clinic notes that a healthy diet and exercise might boost energy during early pregnancy. Source
Ask your provider what is safe for you. Options may include:
- Walking
- Prenatal yoga
- Gentle stretching
- Swimming
- Short movement breaks
5. Improve Sleep Quality
Pregnancy sleep can be disrupted by nausea, bathroom trips, heartburn, anxiety, and physical discomfort.
Helpful habits may include:
- Keeping a consistent bedtime
- Using pillows for support
- Avoiding large meals close to bedtime
- Keeping the room cool and dark
- Limiting screens before bed
- Asking your provider about heartburn or sleep concerns
6. Reduce Nonessential Tasks
You do not have to keep the same pace you had before pregnancy. Simplify where you can.
- Use grocery pickup
- Batch simple meals
- Let laundry wait
- Say no to draining plans
- Ask your partner or support person for specific help
7. Track Your Energy Patterns
You may notice that fatigue is worse at certain times of day or after certain activities. Tracking can help you plan better and explain symptoms to your provider.

- Pregnancy week
- Sleep quality
- Energy level
