Miscarriage in 2011

I kinda recognize pregnancy symptoms as I was once 8 weeks pregnant. Foods I hated I wanted, major gag reflexes. Drank beer (without knowing I was pregnant) would always gag which was odd...Basically it. I never threw up nothing or had morning sickness. 
So now I'm suppose to be having my period on the 29th and it's the first. But I feel nothing? Understand each pregnancy is different...just wondering what's up.
