Introduction
In most cases, sexual intercourse is possible during pregnancy, but caution is advised during the first trimester (first 3 months) and the third trimester (last 3 months). Moderate activity may be acceptable during the second trimester (months 4–6) if the pregnant woman's health is stable. If abdominal pain, bleeding, or placental abnormalities occur during pregnancy, medical consultation is recommended to determine whether sexual intercourse is appropriate. In early pregnancy, embryo implantation is still unstable and the placenta has not fully formed.
Pregnancy usually allows for sexual activity, but caution is advised during the first trimester (first 3 months) and the third trimester (last 3 months). The second trimester (months 4–6) is generally a safer period for moderate sexual activity if the pregnant woman’s health is stable. However, if there are symptoms such as abdominal pain, vaginal bleeding, or placental abnormalities during pregnancy, medical advice should be sought promptly to determine whether sexual activity is appropriate.
In early pregnancy, the embryo implantation is still unstable and the placenta has not fully developed. Sexual activity may stimulate uterine contractions, increasing the risk of miscarriage. Additionally, many women experience discomforts such as nausea, vomiting, and fatigue in the first trimester, making their physical condition unsuitable for frequent intercourse.
During the second trimester, physical discomfort typically decreases, fetal development becomes more stable, and uterine sensitivity is lower. Moderate sexual activity generally does not harm the fetus, but proper positioning is important to avoid pressure on the abdomen. Movements should be gentle to prevent excessive stimulation. In the third trimester, due to the enlarged uterus and fragile fetal membranes, sexual activity may trigger preterm labor, premature rupture of membranes, or infection, so it is generally recommended to avoid intercourse.
Good hygiene is essential during pregnancy to prevent infections. Safe positions such as side-lying are recommended to minimize pressure on the abdomen. Frequency and intensity should be controlled to ensure the pregnant woman feels no discomfort. Emotional well-being should also be considered, and her preferences and comfort must be respected.
