False positive ? 20 dollar test

Me
. The Day after was supposed to start period. Took a test and it was positive. Then took another cheap 3 dollar one and it was positive to. Was waiting until today to say anything to so because we went on a vacation and I figured I would tell him when we got home. But yesterday while camping I started my period. So I'm obviously not pregnant and I'm so hurt I really thought it finally happened ;/
