Negative right?

I was positive I was pregnant. And I'm 4 days late so I took a test today. I had implantation bleeding back in March 1-4 my periods are usually on a 29 day cycle. I was supposed to get my period this month April 1-9 or the 3-11. My periods are irregular. But I've been very off since March. I get so sick and I even get nausea while driving! I have to pee a lot. And my breasts hurt so bad and all my veins on my body are appearing like they want out of my body. And my belly was always flat as a board and now I have a little bump and it's hard all around and down below where the uterus looks like it's swollen up. My belly has been growing. I eat but not an excessive amount.  It's hard to fall asleep at night. And I wake up in the morning feeling like crap. So should I just say I'm not? And continue on with my life. Or get a blood test since it seems like tests don't want to work.
