Implantation ? Late period TMI pic

i Was supposed to get my period 2 days ago. I’ve tested and a faint blue dye positive and then multiple pink including first response early result come up with a bfn . The day I was expecting my period I had some discharge with a pink tinge to it . Then yesterday some brown spotting only when I wiped . This morning I was sure my period was going to begin due to slight cramps and lower back pain . I had brown spotting this morning then a few hours later red blood when I wiped and nothing since .. now after using the bathroom again , I had brown stringy discharge . I’m not sure what to think after getting negatives on the pink dye . Could it be my period still trying to come or possibly pregnant
