Implantation blood?

Hi girls, I'm off pill since last September, first real and only period in December. I'm 6 DPO and my period was due on the 29 Jan. Yesterday when I wiped after I went to the bathroom I had EWCM and some tiny filaments of pinkish blood, both times I went to the bathroom. Could it be implantation blood? I am supposed to test in a week. Thank you
