The second trimester is often defined as weeks 13 through During this time, your baby continues to grow and develop almost daily. This means your belly grows more, and you will notice other changes. The nausea and vomiting from morning sickness should lessen over time. You may have more energy and fewer mood swings as your hormones balance out. This is a good time to tackle many tasks necessary to get ready for your baby.
Eat healthily, take gentle exercise, be kind to yourself and rest when you can. You may be feeling all squashed up inside… or something magical might have happened, and some of your pregnancy symptoms could have vanished almost overnight. This can happen when your baby moves head down into the pelvis, in a staged process called 'engagement'. It frees up space in your abdomen, and gives your lungs a bit of a break, so if you've been feeling breathless, then that should ease off. It also reduces the pressure on your stomach, so symptoms such as heartburn could disappear as well. This drop down is called 'lightening', and for many women, it's a welcome relief.
