Implantation bleeding?

So I woke up this morning. Small amount of red blood mixed with brown in my underwear. Put in a tampon. Red on the applicator. Took the tampon out 2 hours later. Nothing but brown on the tampon. Moderate amount. Put in a new tampon. Nothing on the applicator. Changed it an hour later. Still brown. Light amount. Mixed with some red clot. Glow said my period was due next Monday. So if this is my period, it's a week early and is falling on 9 DPO. What do y'all think? Should I take a test? Or wait and see if the bleeding stops?
