The first trimester is crucial for the baby’s development as all the major organs start to form. At week 4, the embryo is the size of a poppy seed and has already formed the neural tube, which will develop into the brain and spinal cord.

By week 12, the fetus is fully formed, and the sex organs start to differentiate.
