First trimester of pregnancy – weeks 1-13

Learn more about what to expect during your first trimester of pregnancy.

The first trimester includes the time from conception until 14 weeks of pregnancy.

It is a time of new discovery of your baby(ies) to be and many physical changes including nausea and fatigue. Uncertainties can occur with vaginal bleeding and you may need early care for this reason. This is also a time of decision making around pregnancy care, screening tests and implementation of risk reducing strategies for the rest of your pregnancy.
