Individuals who take care of themselves before and after they become pregnant help their babies stay healthy. Although it is never too late to make these healthy choices, many of the recommendations are best started at least three months prior to pregnancy. A baby's health begins even before they are conceived.
If you are planning on becoming pregnant, schedule a visit with your health care provider before you plan to become pregnant to discuss your health or any recommendations for the healthiest pregnancy possible.
Immunizations

Physical Activity
Physical activity contributes to overall health and wellbeing. The Canadian Physical Activity Guidelines (external PDF) suggest 150 minutes per week of moderate to vigorous physical activity for adults aged 64 and under. If you are not already fit, start with 30 minutes each day. A 10 minute walk, 3 times per day is all it takes to make it easier to stay active which can continue while you are pregnant.
