Intercourse in early pregnancy usually does not lead to embryonic abortion, but it may cause contractions due to uterine excitement, which may lead to bleeding, abdominal pain, and preterm abortion. Because the embryo is usually unstable in early pregnancy, when the placenta is not yet grown, during intercourse, it may stimulate the uterus to contract and cause the gestational sac to move down, which may lead to a preterm miscarriage or even an inevitable miscarriage. Most of the embryonic abortions that occur in women in the early stages of pregnancy are due to a decrease in the quality of the fertilized egg or the presence of genetic or chromosomal disorders. Poor endometrial environment, placental problems, women stimulated by unfavorable factors such as smoking and alcohol in early pregnancy, or poisoning by bacteria, viruses, drugs, radiation, etc., may lead to the production of embryonic abortion. If fetal abortion has been diagnosed, it is recommended to terminate the pregnancy as soon as possible and to perform measures to induce labor to avoid infection or bleeding. In early pregnancy, it is recommended not to have intercourse, and at the same time to strengthen nutrition, and to go to the hospital regularly for checkups to observe the health of the fetus, especially for women who have a history of abortion or miscarriage, they should find out the cause of abortion or miscarriage in time, and actively carry out treatment to avoid the recurrence of abortion or miscarriage.
