Congratulations, you have reached your 2nd trimester! This trimester is often the stage of pregnancy that mums-to-be enjoy the most. The first three months were a period of rapid development but the next three will be a period of rapid growth! Your baby will quadruple in weight during the 4th month.

Your baby’s development

Your baby is now around 9cm long.

Their lungs are developed enough to practice breathing movements, even though their oxygen supply comes from you through the placenta and umbilical cord.

At this stage, your baby’s heart is pumping several litres of blood through their body every day. Their other organs have all formed, along with their limbs, muscles, genitalia and bones.

Your Body

As you enter the second trimester, your hormones stabilise and you may notice an increase in energy. Those hormones can have some welcome effects that are becoming more noticeable now.

Your hair may look thicker and shinier, and your nails are likely to grow faster and stronger.

Morning sickness usually fades around this time, making it easier to eat a wider range of nutritious foods and enjoy exercise again. Remember to exercise within your limits, and always talk to your healthcare professional to get their OK first.
