Fluid accumulation below the gestational sac

During pregnancy, women need to have sexual intercourse, and then the male sperm combines with the female egg to become a fertilized egg that enters the female uterus. After the fertilized egg enters the female uterus, it will slowly grow and develop in the uterus. First, a gestational sac must be developed, and then the fetal heart and placenta can be slowly grown. So what is the matter with the accumulation of fluid under the gestational sac?

What is the cause of fluid accumulation next to the gestational sac?

The presence of fluid next to the gestational sac indicates that it has been separated from the uterus. Generally, it is blood accumulation, which means that the gestational sac is not stably implanted in the uterus. This situation does not necessarily cause vaginal bleeding. If there are symptoms of stomach pain or abdominal discomfort, the gynecologist will usually diagnose threatened abortion in this case. You have to be careful. The doctor will recommend treatment to preserve the fetus, pay attention to rest and keep your emotions stable.

If both ovaries are not visible, this is related to your pregnancy period. The uterus has enlarged, and the ovaries on both sides are blocked. There is also the influence of surrounding intestinal gas, so both ovaries are not visible clearly. This is normal and there is no need to worry.

During the implantation of the gestational sac, some tiny blood vessels between the decidua basalis and the decidua capsularis may bleed, forming fluid accumulation. The diameter of the gestational sac is about 2 cm at 6 weeks of pregnancy and about 5 cm at 10 weeks of pregnancy. It is normal for the gestational sac to be located at the fundus, front wall, back wall, upper part, or middle part of the uterus. A round, oval and clear shape is normal. If the gestational sac is irregular in shape, blurred, and located in the lower part of the body, and the pregnant woman also has abdominal pain or vaginal bleeding, she may have a miscarriage.

The gestational sac is the primitive placental tissue, a small embryo wrapped by the amniotic membrane and vascular network. The gestational sac is the initial form of pregnancy. At that time, the fetus has not yet formed, and the fetal heartbeat is already there when the embryonic bud appears. In the second week, the embryo implants in the endometrium. When it develops into the second germ layer, a large cavity called the primary yolk sac appears on the ventral side of the embryonic disc. The yolk sac continues to shrink and degenerate during embryonic development, but the extraembryonic mesoderm on the wall of the yolk sac is the earliest origin of the formation of blood cells, blood vessels and primitive germ cells - the gestational sac, where the fetus will grow in the future.
