Am I pregnant finally?

I am due on my period today, I have been having terrible headaches, I fainted earlier this morning, I have been sick, my tummy is very bloated, I have been constantly needing to wee, I have been really moody, my nipples are so sore I can't even touch them? Am I finally pregnant or is this phantom? I'm due on today but no period and no signs of it coming. Ps did a test 3 days ago which was neg x
