After birth I bled for 2months then stopped till period came at 8months PP (breastfeeding).
IIRC mine for lochia it was a consistent darker maroonish(?) red. Heavy for the first two weeks then normal flow afterwards. For period, 1st period was a heavy flow and lasted 1 whole week before the light brown discharge came (prepregnancy my period only lasted 3 days and no strong flow. Irregular dates as well).
My period became regular (just that it’s now 7 days instead of 3) with no more crazy cramps.
