In terms of gestational weeks, what range does the second trimester cover?

The second trimester of pregnancy is defined as covering a specific range of gestational weeks. It begins at the end of the first trimester and runs through the start of the third trimester. Specifically, this period starts at the 14th week and extends up to the 28th week of gestation. This classification is vital for monitoring maternal and fetal health, understanding ongoing developmental changes, and planning appropriate care and interventions.

The first trimester encompasses weeks 1 through 13, while the third trimester begins at week 28 and continues until delivery, usually around 40 weeks. This delineation allows healthcare providers to track developmental milestones accurately during pregnancy and to provide patients with relevant information regarding their health and the health of the fetus.
