Im so confused

Shelby
So yesterday i thiught i had a false positive because i didnt look at my test till 30 mins later. Well i went and got a clearblue test and had a slight line. Woke up this morning and had a negative and when i got home from work i took this test and within seconds the line showed up. I also laid it on the edge of a cup to help prevent evap line. Then i dipped 2 more and they cane out neg. Wtf is going on :(
