Bleeding the Week After Period (Nexplanon)

I wasn’t sure how to word the title haha but basically, here’s the rundown: so I was on my period from the 14th-25th. The 26th-29th, I was perfectly clear, had normal discharge and everything, but then this past Friday (the 30th), I was hit with what felt like a period again. I know that spotting can be a thing on the implant, but I don’t even know if I can call it spotting? On Friday and Saturday, it didn’t fit the “light” characteristic that comes with spotting, it was like a regular period flow, but then the past two days, it was a little lighter. Basically, what I’m trying to say, is this normal or does it mean anything? i’m sexually active but haven’t done anything since July
