Faulty test

Lawonda • mother of 3❤❤❤

This morning I took a equate pregnancy test from walmart. If prego it would show 1 vertical line in result window and 1vertical line in control window. Mine showed a horizontal line in the result window. I was confused and threw the test in the trash. When my husband called from work I decided to take it out the trash to send him a picture of it. Then I noticed it had two vertical lines. Is this test defective?
