Implantation bleeding???

miranda

I never had this problem before. I usually get sore breasts before period starts but no sore breast this time and my period wasnt due for like 2 more days. I started having brown discharge but it wasnt heavy enough to stain the pads only when I wiped. No cramps usually i get cramps with period. So after two days it stopped and i had like light twinges on my right side like a cramp. Could that be my period or implantation?? Someone please help
