Clinically, an ectopic pregnancy is prone to rupture when the gestational sac is larger than 3cm, and it usually occurs in the 6th or 8th week. This rupture, either large or small, has a lot to do with the location of the fertilized egg’s implantation. Because ectopic pregnancy mainly refers to tubal ectopic pregnancy, so if it is in the jugular or upper part of the fallopian tube, it is mainly common for miscarriage. If it is in the mesosalpinx, it ruptures a little later, but it is also the most dangerous. Also if the pregnancy is in the isthmus of the fallopian tube, rupture is usually possible before 6 weeks. Therefore, when abdominal pain and irregular vaginal bleeding occur, you should go to the hospital as soon as possible to confirm the diagnosis. If the diagnosis is ectopic pregnancy, it should be treated as early as possible, and conservative treatment can be taken in the early stage. Usually choose methotrexate drug intramuscular injection, or with some traditional Chinese medicine to kill the embryo and mifepristone and other drugs for treatment; the later stage may have to take the surgical treatment, take the removal of the fallopian tube, these are also to pay special attention to.
