If there are germs and there is a lot of fluid in the uterus, sometimes it has no effect on the pregnancy, but sometimes it will cause infection, preterm miscarriage, and the embryo stops developing and other hazards. 1. Infection: usually due to the low level of progesterone in the early stages of pregnancy, accompanied by fluid in the uterine cavity, easy to lead to the low immunity of the female body, resulting in bacterial infections. 2. Pre-eclampsia: It is usually due to the fact that the fluid in the uterine cavity will gradually stimulate the uterine cavity, affecting the normal development of the fetus in the mother’s body, and will lead to intrauterine hemorrhage, thus resulting in the phenomenon of pre-eclampsia. 3. The embryo stops developing: it may be due to the fact that the fluid in the uterus can not be absorbed normally around the mother’s uterus, which will easily cause the phenomenon of stopping the development of the fetus. If there are embryonic buds with a lot of fluid, you should go to the hospital in time to avoid delaying your condition.
