What typically happens at 41 weeks
From 41 weeks a pregnancy is late term. Care teams often discuss extra monitoring or induction around this stage.
The third trimester is about growth and getting ready for birth. Appointments usually become more frequent, and it is a good time to think about your birth preferences and practical preparations. You have reached full term.
Every pregnancy is different, and the timing of tests and appointments depends on your healthcare provider and country. If something worries you — for example bleeding, severe pain, fluid leaking or, later in pregnancy, a change in your baby’s movements — contact your midwife, doctor or maternity unit straight away.
