Help! Am I preggoss??

So I'm on my period AND I got a BFN twice! But I'm having nausea (severe; on/off for about a week), lower bilateral back pain, swollen breasts, mood swings (which could be PMS), and finally VERY VIVID dreams which could be a myth more than a symptom of pregnancy. Oh and my temp is 1. higher than normal. Now I've never had any of this with ANY other period for as long as I've had periods! Could I be preggoss???? Please help y'all!!
