Is it safe to have sexual intercourse during the first three months of pregnancy?

Sexual intercourse is generally not recommended during the first three months of pregnancy.

The first trimester (first three months) is a critical period of early pregnancy, during which sexual intercourse is typically discouraged. This is because the embryo is undergoing implantation and initial development within the uterine cavity, making it highly susceptible to adverse external influences. During intercourse, uterine contractions may occur, potentially triggering threatened miscarriage or actual miscarriage. Therefore, abstinence from sexual activity is advised throughout the first three months of pregnancy.

After the first trimester—i.e., from the fourth month onward—the fetus is usually more stably established within the uterus, and sexual intercourse may be resumed cautiously, provided both partners are comfortable and no complications exist. However, intercourse should be gentle, brief in duration, and not overly frequent. Conversely, sexual activity should again be avoided during the final trimester (last three months), primarily to reduce the risk of preterm labor. Accordingly, we recommend minimizing sexual activity throughout pregnancy. It is also important to ensure adequate rest, avoid exposure to harmful stimuli, maintain healthy lifestyle habits, and follow a balanced, nutrient-rich diet.
