I'M SO CONFUSING NOW!!

I have cramping in stomach, nausea, slight headache, dizziness, tired, leg pain, back pain on and off and also I pee a lot for 8 days and my period was due on 2 days ago. I went to the bathroom and I wipe discharge Brown then later bleeding dark red or Brown red TODAY. Is it implantation or period? Or can I be still pregnant?
