pregnant?

I have been having pregnancy like symptoms for like two and half weeks now. Every symptom nausea even but not throwing up. I haven't had my period yet but also don't start till like the 5th so the low cramping doesn't usually happen this early along with very very sore breast! I normally don't get those till two days into my period. I just noticed veins in my boobs a few days ago I took a test but negative? Give me advice and pray that I could be we've been trying for a year.
