Trimesters FAQs

The first trimester starts from the day of conception (when an egg is fertilised by sperm) to about 12 weeks.  This is based on an average gestation of 40 weeks. Apart from morning sickness a lot of what is happening during this trimester is not felt or seen by the naked eye.

The second trimester is from 12 – 24 weeks.  This is based on an average gestation of 40 weeks. The second trimester is often referred to as the ‘honeymoon’ phase as you start to get some energy back and morning sickness eases.  A lot of mums start to see their little bump growing and may even feel first kicks.

The third trimester is from 24 - 40 weeks. This is based on an average gestation of 40 weeks but in reality this final trimester will continue until your baby is born. This is the business end of pregnancy; your baby will be growing quite big now and all the last pieces are coming together in preparation for your baby’s arrival.
