is this positive!!?

I'm not supposed to get my period until next week Monday 1/9 but I have been extremely off lately. My boobs are so sore I can't even have so much as a pillow near them, I have been nauseous, my mood is so up and down I cried my eyes out at a tv show and I have been wanting to do nothing but sleep. I couldn't wait anymore and decided to take a test tonight and I feel like I'm seeing things!
