Could I be pregnant?

I am 26 years old, my hubby is 29 and we've been together about four years now. 
I've been off the pill for maybe six months now and we have been having unprotected sex but we weren't necessarily trying to get pregnant--not to say that we don't want a baby, we'd be thrilled. 
I just don't want to get overexcited and get let down again. ><
I'm only a few days late for my period but I'm not having any of my usual pms symptoms so far either. 
So what do you think?
Yes? No? Maybe?
