Try not to have intercourse in the early stages of pregnancy because the embryo has just settled and is not firmly attached to the uterine wall. Intercourse can cause contractions of the uterus, resulting in bleeding, abdominal pain, and symptoms of preterm abortion. It is recommended to avoid intercourse in early pregnancy even if the movements are gentle. The ovarian corpus luteum secretes progesterone in early pregnancy, which can inhibit uterine contractions. If the corpus luteum is incomplete or atrophied it can lead to low progesterone and symptoms of miscarriage. At this time, bed rest is required and intercourse is absolutely prohibited. In early pregnancy, it is recommended to eat a light diet, avoid greasy and spicy stimulating foods, eat more protein-rich foods, eat more fresh fruits and vegetables, and take appropriate vitamin and folic acid supplements. Avoid abdominal exertion, constipation, etc.
