Pregnancy trimester by trimester: what happens, what is checked, and what to ask

What each stage involves, what the routine checks are for, the warning signs at every stage, and what to take to each visit.

What you will be able to do afterwards

  • Describe what the booking visit involves and why it happens early
  • Say what the routine scans and blood tests are for, in each trimester
  • Recognise the warning signs that mean today rather than the next appointment
  • Prepare questions for a short antenatal visit, in priority order
  • Ask about cost, place of birth and follow-up before the decisions are close

Completing this course means you have worked through the material. It is not a clinical qualification, it does not make you able to advise anyone else, and it carries no professional standing.
