So a few days ago, the first day of my period was completely normal. Like how any other period I’ve had. But the second day and like 3rd day (last day) were just soo little. There was barely anything and it was brown. a normal period for me it usually is the heaviest on the first day but I’ve never had it this light or have brown discharge the whole time. What is going on is this normal to happen once in a blue moon or something else going on?? Someone help
