Whether a painless abortion can be performed on the 46th day of pregnancy depends on whether the patient has an intrauterine pregnancy, normal coagulation, gynecological infection and allergy to anesthetics. Generally the best time to do painless abortion is around 44-55 days of pregnancy. If the pregnancy sac can be seen in the uterus after ultrasound examination, it is clear that the pregnancy is intrauterine, and the pregnant woman has normal coagulation function, does not suffer from gynecological infectious diseases, and is not allergic to conventional anesthetics, then painless abortion can be carried out. But some pregnant women are ectopic pregnancy, there is no gestational sac in the uterus, this situation can not do painless abortion. This is because painless abortion involves suctioning the gestational sac out of the uterus through negative pressure. In addition to abnormal blood clotting function, the presence of infectious inflammation of the genitals and urinary system, as well as allergic to conventional anesthesia drugs, you can not do painless abortion. Otherwise, serious complications such as hemorrhage, uterine infection and anaphylactic shock are likely to occur during the procedure. If you want to have an abortion on the 46th day of pregnancy, it is recommended that you follow the doctor’s instructions to complete the relevant examinations, and then decide whether or not to have a painless abortion based on the results of the examination.
