Month 4: You start to show! Your nipples start to darken and the line running from your navel to your pubic hair may darken (linea nigra). The next few months are usually some of the easiest in pregnancy because the early discomforts have disappeared. You should begin feeling the baby move.

Month 5: Your uterus has now expanded to reach the height of your navel, and the skin of your abdomen stretches. You should definitely feel your baby moving by now.

Month 6: You will begin your period of greatest weight gain. You may experience a stitch-like pain at times down the side of your abdomen as the uterine muscle stretches.
