my period last month was weird. It began with 5 days of a quite light pinkish bleeding (but enough to fill a pad more or less). Then on day 6 I suddenly had what I consider a normal (red blood) and quite heavy 3 day bleed. Then it stopped. Am now trying to calculate when my actual period started. Would the start of the pink bleeding mark the start of that period? Or would the period start date be the heavier 3 day bleed?
