Clinically there is no clear rule on how many times it is better to have intercourse during pregnancy, but it is generally recommended that intercourse be prohibited during the first three months of pregnancy and the three months before delivery. Generally speaking, the placenta of the fetus is not fully formed in the first trimester of pregnancy, so try to avoid coitus, so as not to cause miscarriage. In the first trimester, the fetus has grown in size and intercourse may lead to premature labor, so try to avoid intercourse. In the middle of pregnancy, the fetus is relatively stable, you can have intercourse appropriately, but the number of times varies from person to person. The action should be gentle, avoid squeezing the abdomen, and the time of coitus should be shortened accordingly to avoid aggravating the burden on the pregnant woman. However, if the fetus is unstable, the whole pregnancy should avoid intercourse. During pregnancy, you should pay attention to balanced nutrition, and you can exercise appropriately, but you should avoid strenuous exercise.
