Query: THEY DONT WORK!

I purchased these last week and received a positive result every day! I decided to take them to see what a negative looks like since I KNEW I WAS ON CYCLE DAY 5. Well it was positive and it continues to be positive! Every other test that I bought after this test says negative. I am not scheduled to ovulate in another 13 days or so. I know I would not have so many positives back to back. DON'T WASTE YOUR MONEY!! GO TO EARLYPREGNANCYTEST WEBSITE. Most ppl use those and I haven't heard about any issues.
