12 weeks pregnant

Your baby

Muscles and organs continue developing, and the early skeleton is beginning to harden into bone. Your baby's body is becoming more defined, but there is much more growth and maturation ahead. The plum illustration describes an approximate size; it cannot replace the measurements or interpretation from your own prenatal assessments.

Your body

Nausea begins to ease for some people around this stage, while others continue to feel unwell. Your waist or breasts may be changing, and clothes may fit differently. There is no deadline for feeling energetic or looking pregnant. If symptoms persist, ask for help rather than assuming you have missed the point when things are supposed to improve.

This week

Moving toward the next stage

Use your next visit to review what has happened so far. Ask whether test results have all been explained, whether any decisions are time-sensitive and what care is planned next. If eating, sleep or work is still difficult, put that near the top of your question list. You may also want to discuss activity, travel or telling people about the pregnancy. The guide groups weeks into stages, but your appointments and support should reflect your own health and circumstances rather than a fixed checklist for everyone.
