Spotting or second period??

Alanna

I've had the implant for just over a year now and have been exceptionally lucky to be period-free since having it. Out of the blue, I've had a fairly normal period, but it's been followed nearly a week later by some light bleeding - not enough to soak a light tampon or pad but enough that I've definitely noticed. I've had no other symptoms. Could this be a bizarre second period or just some particularly bad spotting?
