Implantation bleeding

Brittany

So yesterday I may have experienced implantation bleeding... I wiped and it was light pink and brown... then I put a panty liner in and really only brown spotting but still when I wiped it was pink... I had cramps. Last night I put in a tampon just in case and this morning I checked it and it wasn’t really that filled .. i did have blood in the toilet but it was very light pink.. I am honestly not sure if this is implantation bleeding or not.. but my period is 12 days late. The last time I had my period it was feb 24-28 and didn’t have a period at all in the month of March... could anyone help me figure this out and kind of narrow it to either period or implantation ?
