The causes of fluid in the uterus but not bleeding in early pregnancy include external stimulation, endometritis and other factors, which can be eliminated through general treatment and medication. 1. External stimulation: If the endometrium is stimulated by the outside world during the implantation of the fertilized egg, it is easy to have fluid in the uterus without bleeding. However, the exudate is usually small and has little effect on the embryo, so no special treatment is usually needed. In life, it is recommended to pay more attention to rest, maintain a healthy and positive state of mind, and avoid being affected by bad emotions and frequent uterine contractions. 2. Endometritis: Endometritis may also cause fluid in the uterine cavity in early pregnancy, but because the condition is mild, bleeding does not occur. If it does not affect the development of the fetus, you can not take treatment measures for the time being, with close attention and regular review. For patients with severe inflammation, they need to be treated with antibiotics such as amoxicillin or cefazolin sodium according to the doctor’s prescription, so as to avoid the problem of fetal development retardation. Uterine fluid is a common adverse symptom in early pregnancy, and the fact that it has not yet bled indicates that the condition is mild. It is important to pay attention to this problem and go to the hospital as soon as possible.
