A woman who has intercourse during pregnancy will not get pregnant again, even if she is not using birth control. Because the estrogen and progesterone levels are high at this time of pregnancy, ovulation will not occur and there will be no way to form a fertilized egg, so she will not get pregnant again. Of course, intercourse during pregnancy may have some effects on the fetus, especially in the early and late stages of pregnancy, so try not to have intercourse. If the fetus is stable in the middle of pregnancy, you can have intercourse, but be careful not to move too much to avoid affecting the health of the fetus. If the fetus has been unstable, it is not recommended to have intercourse during pregnancy. If you have intercourse during pregnancy, you should take appropriate hygiene measures to avoid infection. Pregnant women should pay special attention to more rest and not to do too strenuous exercise.
