Fluid in the uterus during pregnancy cannot usually be eliminated artificially or by medication, but only by waiting for it to absorb on its own. Fertilization or evacuation of the uterus is required if necessary. As fluid in the uterus occurs during pregnancy, there is no way to intervene artificially or medically to avoid affecting the fetus. Therefore, if the amount of fluid in the uterus is small, it can be absorbed by the woman herself. If the amount of fluid in the uterine cavity is relatively large, it may lead to miscarriage or preterm labor, and at this time, it is necessary to use progesterone medication under the guidance of the doctor to protect the fetus; for the amount of fluid in the uterine cavity is relatively large, and it is impossible to assess the continuation of the pregnancy, it may be necessary to carry out evacuation treatment. For those who have fluid in the uterus during pregnancy, it is recommended that they seek medical attention in a timely manner to avoid serious consequences.
