Implantation bleeding??

My period isn’t expected for 2 more days. Yesterday afternoon I wiped and there was some brown spotting. Before bed I went again and it was bright red only when I wiped, 2x. Went to bed thinking my period had started. Put a tampon in and called it a night. Woke up this morning and there was nothing there. Haven’t had any more the rest of today. Only a few Brown sports again from time to time. Is it implantation or is af just taking her sweet time?
