With my second baby, I had a negative pregnancy test, and the child is 8 years old now, and I still say he's awkward!
I got the test done when I was a couple of days late, and I knew I was pregnant, so when it was negative I waited 2 weeks before doing another, which was then postitive.
If you are pregnant, it would be a bit early for the heartburn and nausea, although you would have tender breasts and going to the toilet quite early.
Let us know how you get on.
My step sister has 6 kids and she for some bizzare reason always gets confirmation by blood test as urine tests always read negative. If you wait a while and still no period but they still read negative I'd book to see your doc. Good luck and keep us all posted. Fingers crossed for you. x
