Ectopic pregnancy can be difficult to diagnose because symptoms often are like those of a normal early pregnancy. These can include missed periods, breast tenderness, nausea, vomiting, fatigue, or frequent urination (peeing). Most people who have ectopic pregnancies go on to have healthy pregnancies. If both fallopian tubes are still intact, or even just one, the egg can be fertilized as normal. However, if you have a preexisting reproductive problem, that can affect your future fertility and increase your risk of future ectopic pregnancy.
