possibly pregnant?

I have always used a condom when having sex with my boyfriend and well, So I'm 7 days late according to eve and two days late according to the 28 day rule I keep on my own. My discharge isn't watery it's thick and white, I'm hungry all the time. Buuuut I don't pee all the time and I have cramps which could mean my period is just taking longer than usual. I'm bloating and my stomach isn't hard. What are some more tell tell signs I should be looking out for before I buy a test.
