help please 😩

Big question ladies. Sorry if this is tmi but I'm desperate. Could this be implantation bleeding? If I'm correct I ovulated on the 25-26th of February . I have a normal 30-32 day cycle. My period is supposed to start Monday the 13th of March. Please let me know. I'm currently experiencing cramps and only had that bit of blood when I wipe. Could I be starting my period or implantation?
