What typically happens at 37 weeks
From 37 weeks a pregnancy is considered early term.
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. Full term starts at 39 weeks — 2 weeks from week 37.
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.
