Under normal circumstances, an ectopic pregnancy is also considered a type of pregnancy, and symptoms similar to early pregnancy reactions may appear, including nausea, vomiting, fatigue, loss of appetite, or breast tenderness and obvious breast enlargement.

However, the presence of breast tenderness does not necessarily indicate an ectopic pregnancy, as normal intrauterine pregnancy can also cause breast tenderness. Therefore, if pregnancy is suspected, it is advisable to undergo prompt medical examinations to determine whether it is an intrauterine or ectopic pregnancy.
