HPT twice daily?

Celeste • Pregnant with baby #1 EDD April 3rd, 2016!
I am 8 DPO and I am a POAS addict. I am currently taking 2-3 pregnancy tests a day. Husband says I am crazy. I just keep thinking maybe THIS time it will be positive. Am I alone in this craziness? Please tell me there are others like me out there! This TWW is hell!
