There : There is a chance, due to lower pregnancy hormone levels, that an ectopic pregnancy will go undetected via a urine pregnancy test.
If you suspect an ectopic pregnancy and are experiencing signs/symptoms (lower abdominal pains, vaginal spotting, missed period) you must seek medical attention right away.
The pregnancy can be verified via a blood test, and ectopic via ultrasound. An ectopic pregnancy can be life threating, causing fallopian tubes to rupture and bleed.
Other reasons for a missed period can be increased physical activity, stress, hormonal changes and malnutrition.

Yes: Urine pregnancy test have improved in sensitivity of the last 10 years however, if you body didn't secret enough of the urine pregnancy hormone yet ( sometimes 3 days too early)..; you may get a negative test whereas if you waited a few more days it would have been positive.

Ectopic: Ectopic pregnancy produces the same hormone as regular pregnancy. There is no way to distinguish the two pregnancies by blood testing.
