Possibly pregnant?

My ovulation day’s were in the beginning of the month, and my period is due on Saturday. Every since my ovulation ended, I have been feeling so weird. I would get times where I would literally eat everything and times where I can’t at all without feeling sick to my stomach afterwards! Black pains, growing breasts, fatigue, drowsiness, and very emotional to the point where I would cry about the littlest things. I am as well super bloated. Could it be possible that I am pregnant?
