What is first trimester?

The first trimester of pregnancy is the first 12 weeks of pregnancy, starting from the first day of the woman's last menstrual period. During this time, the fertilized egg implants in the uterus and begins to develop into an embryo. This is a critical period of development for the baby, as major organs and body systems begin to form. Many women experience symptoms such as morning sickness, fatigue, and breast tenderness during the first trimester. It is important for women to receive prenatal care during this time to monitor the health of both the mother and the baby.

The first trimester of pregnancy is the period from conception to week 12. During this time, the embryo implants in the uterus and begins to develop into a fetus. The major organs of the fetus begin to form, and the placenta develops to provide nourishment and oxygen to the growing baby. The first trimester is also a time of significant hormonal changes for the mother, which can lead to symptoms such as nausea, vomiting, fatigue, and breast tenderness.
