In prenatal follow-ups, we examine pregnancy in three stages. The first trimester is the early period of pregnancy, where steps are taken to ensure a healthy pregnancy by bringing maternal diseases under control. Basic tests are performed, and the presence of fetal anomalies can be investigated through the measurement of nuchal translucency, which we call first-trimester screening. In the second trimester, anomaly scans are completed, and blood tests, including the oral glucose tolerance test, are repeated. The third trimester is the period when the mother’s physical burden increases, the baby’s development is finalized, and the decision for the mode of delivery is made. These three-month periods in pregnancy follow-up have distinct characteristics, and follow-ups should continue in line with the physician’s recommendations at each stage. Prenatal visits are generally scheduled at intervals of 2–4 weeks, and more frequent monitoring may be initiated if a problem is suspected. A healthy delivery is more attainable through a healthy and controlled pregnancy follow-up process.
