Too soon for period?

Sarah

I took Misoprostol for a missed miscarriage on Oct 25th. Bled on and off for about 1 week, then very mild brown spotting for maybe a week later. Had nothing for 2 weeks but today I started bleeding again. Started brown but now red and period-like. No clots. Faint positive on a hpt yesterday morning so I still have some hcg left in my system. Is it possible that this is my period or just residual from the miscarriage?
