Four hours

So I've taken five tests and they all came back negative. I've been feeling cramping and achs so I've been expecting AF she's due in two days, just to humor my self I took a test this moring I got a faint positive. I don't want to get to excited over this but could this really be my rainbow baby. So I have four hours till I'm off work and I can buy a first response but beyond over joyed. I hope this is true :D
