How does an ectopic pregnancy and ovarian cyst affect an at home pregnancy test?

Jessyka asked:


Two weeks ago I experienced my first cramps and still am feeling them mostly on the left side. I feel tired. And my period is now 7 days late. But I’ve taken 4 pregnancy tests in the last 3 days and all are negative, I’m not stressed my school is currently in fall break. My last menstrual was on sept 9.
What do you think.
