Exhaustion in the first week of pregnancy

Early pregnancy can bring tiredness before other symptoms appear. However, the first week may be counted from the start of the last menstrual period, before conception has occurred, so timing can be confusing. Lack of sleep, stress, a viral illness, dehydration or anaemia can also explain low energy. Fatigue is not a reliable way to date a pregnancy or judge how it is developing.

Prioritise sleep, regular food and fluids, and reduce demanding tasks where possible. If pregnancy is possible, take folic acid as advised, avoid alcohol, and check any prescription, over-the-counter or herbal product with a pharmacist or clinician. A home pregnancy test is more useful around the expected period; follow its instructions and repeat or arrange testing if the result is unclear.

Seek urgent help for severe one-sided abdominal pain, heavy bleeding, shoulder-tip pain, fainting or marked dizziness, particularly if pregnancy is possible. Contact a clinician for fever, persistent vomiting, breathlessness, chest pain, confusion or exhaustion that is sudden and disabling. Arrange routine care if tiredness continues, worsens or comes with pale skin, palpitations or breathlessness.

Ask when to test, which supplements are appropriate, and whether existing conditions or medicines need review. Share the date of your last period, cycle pattern, sleep, bleeding, pain and any symptoms such as vomiting or dizziness.
