Think I got my period back already at 5 weeks PP


Pretty sure I may have gotten my period already. I have been spotting brown for the last 2 weeks and no cramping or anything. .

Now I am bleeding bright red and have menstrual like cramps. Super confused because I thought the earliest periods come back is 6 weeks pp and I will be 5 weeks this Monday. .. any thoughts on this ? I am breast feeding too.
