There is no direct relationship between intercourse during pregnancy and cloudy amniotic fluid. Even if you have intercourse during pregnancy, semen will not directly enter the amniotic fluid because the amniotic membrane is like a balloon wrapped around the amniotic fluid and the amniotic cavity is a sealed environment, which is not connected to the vagina. Semen cannot enter the amniotic cavity after intercourse, so even if the amniotic fluid becomes cloudy, it is not considered to be related to internal ejaculation during pregnancy. The main cause of cloudy amniotic fluid is the contamination of the amniotic fluid and feces, which can be caused by intrauterine infection, fetal distress, etc. Therefore, if you find cloudy amniotic fluid in late pregnancy, you should go to the hospital in time. In addition, it is best not to have sex during late pregnancy, because it will increase the risk of infection or premature rupture of the membranes.
