There is usually hope for an irregular pregnancy sac at 6 weeks of pregnancy. Under normal circumstances, the gestational sac of a pregnant woman usually appears round or oval, and if the sac is irregularly shaped, the embryo may stop developing, or there may be a preterm miscarriage. Pregnant women are advised to undergo a blood test for human chorionic gonadotropin (HCG) and an ultrasound to check the condition of the gestational sac. If the human chorionic gonadotropin value is relatively low, but fetal buds and cardiovascular pulsations can still be observed in the ultrasound examination, there is still hope, and fertility preservation treatment can be taken. However, it should be noted that if the value of human chorionic gonadotropin is very low, and no fetal buds and cardiovascular pulsations can be observed, it is meaningless to force abortion preservation at this time, and it is necessary to take the procedure of removing the uterus in time. It is recommended that patients with irregular gestational sacs in the 6th week of pregnancy go to a regular hospital and take relevant treatment measures under the guidance of a doctor.
