pregnancy or period symptoms

Hi, I've been having symptoms but I don't want to talk myself into thinking I'm pregnant. I am suppose to start in 7 days. I have been light cramping, nausea, dizziness, gas, abdominal pain, really hungry, urinating more often (like I used to go 3 times a day now I go about 7-8), angry, super tired, thick creamy white cf. My breast are not super sore but have some soreness. what do you all think?
