You should not have intercourse before the third month of pregnancy or after the seventh month, during which time you can have intercourse under the guidance of your doctor. During early pregnancy, coitus during the first trimester increases the risk of miscarriage due to the unstable development of the embryo, so coitus is not allowed at this time. It is also not recommended to have intercourse after the 7th month of pregnancy to avoid increasing the risk of premature rupture of membranes and preterm labor. During mid-pregnancy, it is important to be gentle and not to have intercourse too often. During pregnancy, you should take obstetric checkups on time under the guidance of your doctor, avoid heavy physical labor and strenuous exercise, and maintain a moderate amount of moderate-intensity physical exercise, such as walking and yoga during pregnancy, to ensure appropriate weight gain, prevent the occurrence of macrosomia, postpartum hemorrhage, and other risks, which is conducive to a natural delivery.
