Am I pregnant?

My period is due on the 2nd of February, I've already noticed a few symptoms but so far It's been near impossible to tell from a regular home test. (I have a lot of cheap tests) My breasts have become swollen and my nipples are really red and starting to brown on the areola. I've also been feeling a little but sick lately but I'm unsure if that's to do with this or if I'm being paranoid. I did have a slight bleed when I wiped but I haven't had anything else like that so far, would it be possible to get a blood test or should I wait it out?
