Whether or not a small gestational sac will result in fetal arrest needs to be judged according to the cause of the small gestational sac. If it is caused by factors such as a late pregnancy, this situation basically will not result in fetal arrest, but if it is caused by other diseases and other factors, the chances of fetal arrest will be increased.
If a woman ovulates late, the conception will be later, so after pregnancy, the gestational sac will be smaller compared with the same time of menopause, this situation is also considered normal, as long as the maternal ketones and blood chorionic gonadotropin is normal, the chances of abortion is very low, you can after a week to carry out ultrasound examination again.
If the small size of the gestational sac is due to some illnesses, such as ovarian hypoplasia, thyroid dysfunction, or sperm problems in men, the chance of abortion will be much higher, and the levels of progesterone and chorionic gonadotropin will be relatively low, in which case more attention should be paid to it, and abortion is very likely to occur.
It is recommended that women go to the hospital for prenatal checkups on time after pregnancy to ensure the healthy development of the fetus to the greatest extent possible, and if abnormalities occur, they should be given timely and appropriate treatment to avoid accidents.
