The presence of uterine bleeding during pregnancy suggests the possibility of preterm miscarriage, because during pregnancy, if progesterone, estrogen or even HCG drops, causing bleeding around the gestational sac. However, the presence of fluid around the gestational sac does not necessarily mean that a miscarriage will occur. If it is relatively small, you can go home and take certain oral medications to protect the pregnancy, such as birth control or progesterone. However, if the fluid around the gestational sac is more, above two centimeters or even three centimeters, it suggests hospitalization for fetal preservation treatment. During the period of fetal preservation, do not engage in strenuous activities, rest in bed and keep your bowels open to avoid causing more uterine bleeding. After a period of treatment, the uterine bleeding has a tendency to become less when reviewed, which will not affect the health of the fetus and can be successfully preserved.
