pregnant maybe?? idk!

So last month my period came a little early, it was kinda light and was shorter the normal. About a week after it ended I was nauseous for a couple of days, so I took a test it was negative. Lately I've been dizzy, and bloated and now it seems like I can't sleep. I'm wake up all the time because my lower back is hurting. I haven't had any symptoms of my period starting. I took a test about 3 days before my period was supposed to start and it was negative and now my period is late. I was just wondering if I should test again or wait a couple of more days.
