Spotting after AF and mc

Hi ladies! I miscarried 6 weeks ago. Got AF about 4 1/2 weeks after. So today is CD12. This morning I'm spitting red again. Is this usual? I never spot between cycles. Going to call my OBGYN today to talk and I have to schedule another blood draw. My hcg was at 26 the day before I got AF.
