Abdominal pain can be ectopic pregnancy?

Abdominal pain during pregnancy is not necessarily ectopic pregnancy, but may also be caused by other reasons. If B-ultrasound finds pregnancy sac and fetal heart, it indicates that it is not ectopic pregnancy, it may be threatened abortion or abdominal pain caused by acute gastroenteritis, etc. If it is severe tearing abdominal pain, bleeding without pregnancy sac may be ectopic pregnancy.
