Pregnancy Pregnancy typically lasts 40 weeks, counting from the first day of a woman’s last menstrual period, and is often referred to in three parts, called trimesters. The first trimester lasts 12 weeks, the second trimester from 13 to the end of 27 weeks, and the third trimester from 28 to 40 weeks.

Certain important milestones in pregnancy occur during each trimester. For example, specific tests are done during the first trimester, and certain problems, if they develop, almost always arise during the third trimester. Although there is nothing crucial about these trimester divisions, they do help both you and your doctor in planning the management of your pregnancy.
