Help? Negative test but no period.

Average cycle length- 26
​Cycle day-52 
​End of last period- May 26th
​I've been bloated since the second week of June and it hasn't went down. I thought nothing of it because I was expecting my period in about two weeks. It never showed up. I've had sore breasts on and off and I pee a lot more than usual, I get nauseous a lot, especially if I don't eat as soon as I wake up. I'm due for my period tomorrow but I have this feeling that it's not going to come. What should I do?
