Second trimester of pregnancy

The second trimester runs from week 14 to week 27. Nausea often eases, energy returns, your bump starts to show, and you will begin to feel your baby move.

Your baby in the second trimester

Your baby grows quickly, starts to hear sounds, practises breathing and swallowing movements, and develops fingerprints, hair and fat under the skin. By the end of this trimester your baby has regular sleep and wake cycles.

Common symptoms
