Because my period had been absent, and i had symptoms. the first i took around 7 pm it was false. The second i took first thing in the morning around 7 am. I waited about 2 minutes maybe less it said negative so i threw it in my drawer, i went to throw it away (12hrs later) and the test read positive?? i read these could be false positives but wouldn't the first test do this since they came in the same box?? i'm hoping for false positive but maybe a little insight, i am however going to take another one in the am
