How many weeks will the gestational sac fluid disappear?

During pregnancy, pregnant women need to undergo regular physical examinations to understand their own condition and the development of the fetus. Some women are found to have fluid accumulation in the gestational sac. Because they don't understand the situation very well, they hope that the body can absorb the fluid on its own and are very concerned about how long it will take. So, how many weeks will it take for the gestational sac fluid to disappear? Let’s take a look below.

If color ultrasound reveals fluid accumulation around the gestational sac after the patient becomes pregnant, threatened abortion should be considered. The main possibility of fluid accumulation is intrauterine bleeding. How long it will take for the fluid accumulation to subside depends on the patient's specific situation. If active pregnancy preservation treatment is carried out, the effect will be very good. If there is not much fluid accumulation, it can be absorbed in about a week.

If the patient has fluid accumulation in the uterine cavity, it is mainly because the implantation position of the gestational sac is not good, such as the implantation position is too low or other factors lead to threatened abortion, and the effect of pregnancy preservation treatment is not good. The fluid accumulation may exist for a long time or increase in amount, or directly cause miscarriage.

Therefore, there is no uniform standard for how long it will take for the gestational sac fluid in the uterine cavity to subside. Regular observation is needed based on the clinical manifestations. While actively preserving the fetus, attention must be paid to vaginal bleeding.

What is gestational sac effusion?

Fluid accumulating in the gestational sac can easily cause miscarriage in pregnant women, so first of all, we need to know what fluid accumulating in the gestational sac is and what its symptoms are.

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.

Why is there fluid accumulation next to the gestational sac?

Whether the condition of the gestational sac is normal directly affects the normal development of the embryo. If fluid accumulates in the gestational sac, miscarriage may occur.

If you have an ultrasound after you become pregnant and it shows fluid accumulation next to the gestational sac, it means there is bleeding around the gestational sac, which means you may be experiencing threatened abortion.

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, but I don’t know if you have symptoms of stomach pain or abdominal discomfort. Generally, in this case, the gynecologist will diagnose threatened abortion.
