8 weeks pregnant without a fetal heart what is the reason

If there is no fetal heart in eight weeks of pregnancy, it can be determined that the embryo stops developing and missed abortion. The main reasons are as follows: hypothyroidism, luteal insufficiency, embryo chromosome abnormalities, immune system diseases, etc. After the diagnosis of embryo stops developing, it is recommended to terminate pregnancy in time. Because the embryo stops developing, it may cause abnormal coagulation function, and it is easy to cause a large amount of vaginal bleeding during abortion. Therefore, it is recommended to be hospitalized for abortion. Before abortion, relevant examinations should be improved, especially coagulation function tests, and preparations for blood preparation and transfusion should be made.
