Tiredness in the first trimester

Progesterone can make you sleepy, while your body begins supporting the placenta and changing blood flow. Poor sleep, vomiting, reduced food intake, or emotional strain can add to the feeling. Fatigue alone does not confirm pregnancy or identify a particular condition. If it is marked or continues beyond the expected early-pregnancy pattern, a clinician may consider Anaemia, thyroid problems, infection, or another cause.

Rest when you can and lower non-essential tasks for a while. Eat small, regular meals containing protein and iron-rich foods, and drink fluids often, especially after vomiting. Gentle movement may help stiffness and sleep, but stop if you feel faint or unwell. Take only pregnancy-safe medicines or supplements that your maternity clinician has recommended; do not start high-dose iron or vitamin products on your own.

Arrange medical advice if exhaustion prevents normal activities, is getting worse, or comes with breathlessness, palpitations, fainting, fever, persistent vomiting, severe headache, or very little urine. Seek urgent help for collapse, chest pain, severe shortness of breath, or heavy bleeding. These warning signs need assessment regardless of whether tiredness is common in early pregnancy.

Ask whether your symptoms and pregnancy stage fit the usual pattern, whether blood tests are appropriate, and which foods or supplements are suitable for you. Mention vomiting, bleeding, sleep problems, low mood, or medicines so the assessment includes the full picture.
