Curious / spotting etc

A

I’m around 12-14 days late on my period. I bought two tests today plan on testing in the morning. I’ve been cramping all day and weekend. I went to the bathroom, wiped and it was light pink color. Could it be possible to have been later his month and this is implantation bleeding? Spotting? It’s not came at all and only came out of me once. I put a pad on but nothing is in it anytime I go to the bathroom, just when I wipe its very light.
