During pregnancy, sexual intercourse is a topic that needs to be treated with caution. To ensure the safety of mother and baby, it is recommended to avoid sexual intercourse during pregnancy, especially in the first and third trimesters. If you really need to have sex, you should choose some relatively safe positions, such as side-lying position, woman on top, man on bottom, etc., to avoid pressure on the abdomen. At the same time, pay attention to gentle movements and avoid violent or sudden movements to reduce potential risks to the fetus.
