Is it safe to have sexual intercourse during pregnancy?
Generally speaking, pregnancy refers to gestation. During the second trimester, sexual intercourse is usually permissible to some extent. However, during the first and third trimesters, sexual activity typically needs to be reduced or avoided altogether. The detailed explanation is as follows:

During the second trimester, the fetal condition is relatively stable, and the placenta has fully developed, resulting in a relatively low risk of miscarriage. At this time, pregnant women can engage in sexual activity appropriately, but should pay attention to intensity and frequency, avoiding excessive stimulation of the uterus. Additionally, pregnant women should choose comfortable positions and suitable environments for sexual activity to ensure comfort during intercourse.
In the first and third trimesters, due to the sensitivity of the fetal condition, sexual intercourse may increase the risk of miscarriage or preterm birth. Therefore, it is recommended to reduce or avoid sexual activity. This principle should especially be strictly followed in cases where there is a history of threatened miscarriage or preterm birth.
If any discomfort occurs during sexual intercourse, such as vaginal bleeding or abdominal pain, the pregnant woman should stop immediately and seek medical attention promptly. At the same time, maintaining cleanliness and hygiene of the external genital area is also very important to reduce the risk of infection.
