Your 1st Trimester Nutrition Guide

A lot happens during the first three months of pregnancy. The fertilised egg rapidly divides into layers of cells and implants in the wall of your womb where it carries on growing and at this stage is called an embryo.

By six weeks, a heartbeat can usually be heard and by the end of week 12, your baby's bones, muscles and all the organs of the body have formed and is now called a foetus.

In the beginning a structure called the yolk sac provides nutrients to the growing embryo. Then after around 12 weeks the yolk sac shrinks and the placenta, now completely formed, takes over supplying nutrients all of which are supplied by the mother so it is important she eats a nutrient dense diet. 

As with preconception all nutrients are important, however, there are certain vitamins and minerals which play more of a vital role during pregnancy.
