Can't tell if I'm imagining it

So, I took a test when I was one day late, and another when I was three, and both were negative. Now I'm five days late and I'm still really tired all the time, with pretty sore boobs, and I think I've been feeling nauseous on and off, but it's not really strong. I don't know if I'm just wishing it would happen, so I feel it, or if it's actually a symptom 😞
