Intrauterine fluid in early pregnancy can have an effect on the fetus and requires active treatment, such as oral medication and intravenous fluids. Fluid in the uterine cavity of a pregnant woman often suggests that the gestational sac is unstable and bleeding exists around it, which may lead to preeclampsia or even progress to miscarriage. In addition, endometritis and cervical canal adhesions may also cause fluid in the uterus, which may have a certain effect on the fetus, but as long as active treatment, the fetus develops normally and can still be delivered. Therefore, pregnant women who find fluid in the uterus should actively cooperate with the treatment. If the amount of fluid in the uterine cavity is small, less than 2 centimeters, oral medication can be used for fertility preservation. During the period of fertility preservation, pregnant women should rest in bed as much as possible, and should not engage in strenuous activities. At the same time, she should eat a light diet and keep her bowel movements clear, so as not to aggravate the bleeding by straining the bowels.
