Positive and then negatives?


So I took a test and it came out clearly positive but being insecure I took one later that afternoon and i took a digital that was negative at like 1 pm. Then the next day, which is today, it said negative again (I tested at like 2 pm) with a non digital, but AF is not here. I'm at least 10 days past and have had your typical early pregnancy symptoms start up in the last few days like nausea, mild cramping, sore boobs and fatigue. I've never fully missed a period like this either. Has this happened to any of you?
