Before getting my HPT i was the same! I think i was probably worse if anything.
The week i was due i had come down with a bad cold and wasn't sleeping properly, so that combined with stress from work i had just assumed i was late (well now so, at the time i didnt even notice i was late, i was too sick to care).
In the week i was due, i was really crampy and cranky as all hell, i think i was more hormonal than ever. But i also had nausea, light-headedness, headaches, frequent urination to add to it. DR told me i had a virus, but a week later i've realised i'm late and i'm still waiting and thought better do a HPT. And BFP it was. Later told the cramps (worse than usual) must have been the effect of my uterus growing so rapidly early on...
