So on the 22nd I was 2 days late I took a cheap test from Walmart faint positive so I took a 5 day sooner test clear positive, I wanted to use fmu so next morning I took 5 days sooner and it was positive! I wanted to confirm w blood so I went and they said it was negative, so I went to health dept they took urine and said it was negative as well, so I went home bought 3 more test. I took a dollar tree one it was faint positive, and took a clear blue 5 day sooner and it was faint positive. So I wokeup this morning took the same dollar tree it was negative and the digital said not pregnant!! This is stressing me out. What it going on! 😢
