I think I had mine last week (at 6 weeks pp) I combi fed up until then, it was light, and lasted maybe a day or 2 ? Im a bit unsure because I was still losing lochia up until a few days before af, and the only reason I think it was a period is because it was more like menstrual blood with some clots (sorry tmi) I also felt quite premenstrual in the days before! goodness knows when the next one will arrive!
