I'm not sure If I'm pregnant can anyone put a few words of help for me on your opinion?

I'm 10 days late, but I've been twelve days once and I thought I was pregnant then but two test came out negative. But my breast are off and on sore, particularly where they, uh, are attached to the body, some days I feel like I just don't know why I feel funny it's almost like I feel like I have a cold, i just have that blah kind of feeling, I do hVe cravings but I have that before my period too. I'm pretty much always tired even when I sleep good which isnt quite normal fir me, and I'm Hungary a lot more than normal, if I'm pregnant it'll be about 5 weeks, any opinions? Am I just syking myself out or what?
