Intercourse is generally permitted in mid-pregnancy and is not recommended in early and late pregnancy.
In general, it is possible to have intercourse in the middle of pregnancy (April-June), but not in the early (January-March) and late (July-September) stages of pregnancy.
1. Early pregnancy (January-March): The embryo is at the stage of implantation and development, so the stimulation of the uterus during coitus may lead to miscarriage.
2. Mid-pregnancy (4-6 months): the fetus is more stable during this period, so you can have intercourse occasionally, but the action should not be too violent, but if there is a placenta praevia and other risk factors, you should not have intercourse.
3. Late pregnancy (July-September): During this period of rapid growth of the fetus, coitus will lead to contractions and thus cause premature labor, and will lead to the possibility of intrauterine infection.
