Could I be pregnant??

I'm five days late on my period & I don't even feel like i'm going to get it. I've had sore boobs, my stomachs bloated, i'm peeing nonstop, my boobs feel heavier, and i've been really tired. I've taken two tests and they were both negative.. I just really feel pregnant though. I took my first test 2 days after my missed period and the second one tonight 5 days after missed period. What do you ladies think? I would be around 5 weeks if I was, should I be getting a positive test if I was that far along!? With my first pregnancy I got a positive test instantly and I was 6 weeks, it ended in miscarriage a week later unfortunately.
