Implantation bleeding?

Okay so my hubby and I did the deed during my ovulation time according to my glow calendar. However, I took an ovulation test that same day and I was not ovulating so I am assuming we missed it this month. However, it is now 8-9 days before my period is suppose to start and I’m bleeding some and having some light cramping. Could this be implantation bleeding or could my period be coming THIS early? I’ve never had my period come this early if so. Thought I would reach out to you all. My mind is going crazy. I think it’s too early to take a pregnancy test right?
