Your Pregnancy: Week 5

Your pēpi is the size of an apple seed.

By week 5, your baby is now around 2mm in length but growing rapidly each day. It’s the size of an apple seed.

The embryo comprises of three layers which will eventually form your baby’s bodily organs. This week, the neural tube (the part that will become your baby’s brain, spine, and central nervous system) is developing, as is the heart. The placenta/whenua is also developing to be your baby’s source of nourishment during pregnancy.

For most people, your period is now a week late and you may start to feel pregnant. Some pregnant people don’t experience any symptoms but for those that do, common ones include increased frequency of urination, mood swings, tender breasts, fatigue, food cravings or aversions, and nausea.
