If the ultrasound indicates that the gestational sac is low, but the shape of the gestational sac is regular, the fetal heart is normal, the germ is developing normally and the tension is good, the fetus can be considered to be kept. However, if the ultrasound indicates that the gestational sac is low, the shape of the gestational sac is irregular, there is no germ in the gestational sac or there is a germ and no fetal heart, such embryos have a higher risk of miscarriage and the pregnant woman should pay high attention to it and cooperate with the doctor for active treatment. The main reasons for the low position of the gestational sac are as follows: 1, often do intrauterine surgery: such as scraping surgery, multiple abortions, etc., will lead to a thin endometrium, and the gestational sac will often choose the part of the thicker endometrium, so it is easy to cause the low position of the gestational sac; 2, scar uterus: for example, had done myoma removal or cesarean section, will form a scar uterus, scar uterus The scarred uterus is a common reason for the low location of the gestational sac; 3, fibroids: if a woman has gynecological diseases such as fibroids in the uterine cavity and fibroids in the endometrial area where the bed can be normally laid, it will also lead to the low location of the gestational sac; 4, genetic factors: it is also common for her genetic factors to lead to the low location of the gestational sac. The risk of miscarriage is higher when the gestational sac is low, so once there is pain in the lower abdomen or vaginal bleeding, you need to go to the hospital in time to keep the baby, but you also need more rest during the process of keeping the baby. It is recommended that pregnant women eat nutritious foods to strengthen their bodies.
