Implantation bleeding?!

I’m 11DPO today and I never bleed this early before my period is due! It’s not really getting any heavier at this moment!! So is this it? Is this implantation??? It’s 5:03 pm if that helps! (My symptoms are slight cramping, sore/tender/swollen/full boobs, nipples are a little darker, nausea, headaches, and tiredness.)
