I need your opinions, are these true signs of pregnancy?

Before he mentioned that I have been really tired, peeing every other hour or more, all around exhausted, my cm has been in overload, (doing laundry a lot more now) and I've been light headed or dizzy, I snapped at someone that I work with for a petty mean comment they made, usually I ignore it. And when a customer swore at me I wanted to cry. I have a light headache a lot of the time and my hips and lower back hurt a lot and make it hard to sit or stand up. Also I have been very bloated, my stomach feels like a balloon. 

I took a test a month ago and got a negative result, a week after that I got my period. And my period is due this week, it's Tuesday and I haven't gotten it yet. I'm slightly crampy, more just constipation.
