- The third trimester of the pregnancy, the period between the fourth month and the sixth month (the fourteenth week until the twenty-seventh), the growth and development of the fetus is monitored.
- The third trimester is the period between the seventh month and the ninth month of pregnancy (the 28th week until the fortieth week). At this stage, the fetus has developed enough to survive without medical aid outside the woman’s womb.
- In the first stage, the fetal heartbeat can be heard. In the second stage, the woman feels the movements of the fetus for the first time. In the third stage, the pregnant woman may undergo contractions known as Braxton Hicks contractions in preparation for childbirth.
