So AF is due in 3 days, I am almost certian that I might be pregnant. Everything started on Tuesday/Wednesday, I got so dizzy that I almost passed out then Thursday morning while at work  the sane thing happened I had to sit down and eat something and once I did I was okay, I have been peeing it seems like every 2 hrs or so, I have been having mad hot flashes, not to mention my boobs are very full and kind of sore. So my question is if I am testing before I miss my period should I use FMU?
