Implantation bleeding??

I stopped my birth control in June and had my last period in July. I haven’t been <a href="https://play.google.com/store/apps/details?id=com.glow.android">tracking ovulation</a> because I feel like it’s useless at this point. The last time me and my husband BD was a week ago. Well, last night I was cramping a little but didn’t think much of it. This morning when I used the bathroom I wiped and there was a little bit of blood. But no more since then. And I’ve been cramping some today too. Could this have been implantation bleeding or the start or my period???
