What is trimester in pregnancy?

Pregnancy is divided into three trimesters, each lasting approximately three months. The first trimester (weeks 1-13) is marked by significant hormonal changes, fetal organ development, and early pregnancy symptoms. The second trimester (weeks 14-27) often brings a sense of increased energy and reduced nausea. Fetal growth accelerates, and fetal movements become noticeable. The third trimester (weeks 28-40) involves continued fetal growth and preparation for birth. Each trimester brings its own set of physiological and emotional changes for both the mother and the fetus. It's essential to receive appropriate care during each trimester.
