I am 16 days out from a repeat C Section/tubal. The past 3 or 4 days I have had no postpartum bleeding and really the entire week before it was super light. Now today all of a sudden I am bleeding very heavily like a period and (TMI) it is dark red/brown. Could this be my period this soon after giving birth? Or if not, something serious? I think my period came back at 5/6 weeks with my first which is why I am surprised if that is what this is. Also, I am not breastfeeding and I don't have any cramps or anything currently.
