Fluid accumulation around the gestational sac at 7 weeks of pregnancy is not normal and may be due to causes such as preeclampsia or subchorionic hemorrhage, and treatment should be prescribed according to the symptoms. When ultrasound suggests fluid around the gestational sac at 7 weeks of pregnancy, it may be due to causes such as preeclampsia or subchorionic hemorrhage, which is not normal. For those with symptoms such as vaginal bleeding, abdominal pain and decreased levels of progesterone and blood HCG (human chorionic gonadotropin), it is necessary to follow the doctor’s instructions to give progesterone and other medications to preserve the fetus, and to repeat the examination on time. However, when the ultrasound indicates that the amount of fluid around the gestational sac is small and the development of fetal buds and heart is good, the progesterone and blood HCG levels are normal, and there are no symptoms, you can pay attention to the doctor’s advice to take proper rest, prohibit coitus, and do ultrasound review after 1 week. Due to the unstable development of the embryo in early pregnancy, it is important to pay attention to not engage in heavy physical labor and strenuous exercise, continue to take folic acid, and increase dietary nutrition appropriately. When 7 weeks pregnant ultrasound examination suggests that there is fluid around the gestational sac need to be given treatment under the guidance of the doctor.
