What typically happens at 25 weeks

The baby is putting on fat and the skin is becoming less translucent.

The second trimester is often the most comfortable stretch. Energy usually improves, the bump becomes more noticeable and movements become easier to feel as the weeks go by. At 25 weeks there are about 3 weeks until the third trimester starts at 28 weeks.

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.
