Mid cycle bleeding

I'm 48 and have always had regular, 28-30 day cycles.  This cycle, I started bleeding heavily on cd17-21. This bleeding was bright red, heavier than my normally heavy periods, and accompanied by cramping.  It is now decreasing to just spotting.  This has never happened to me before.  

I'm scheduled in a week for an endometrial ablation for heavy periods.  Should I mention this abnormal mid cycle bleeding to my doc before the procedure, or just assume it was a weird perimenopausal thing?  I did cal the office, but only spoke to the nurse who said not to worry about it at all.  While my periods are heavy, I've never had midcycle bleeding at all.  I'm just a little worried that the ablation will make it difficult to detect if a problem is developing.  

Thank you.
