We were actively trying to conceive. I decided to buy these because I would not feel guilty about taking as many as I wanted since they are so cheap. I thought I had found a great deal that would help keep me calm during the waiting game of trying to conceive. I took at least 8 of these the correct way, waited the 5 minutes, and all negative. I kept feeling like I was pregnant though, I just knew there was something off with my body. I came back and read the negative reviews, decided I should give another type of test a chance and see. I bought the first response and instantly I received a positive result. This was five days after my missed period so these tests should have shown positive according to their directions. Please save yourself the frustration and buy a different brand.
