What Causes Delay In Periods While Being On Triphala?

My last period was on 21st February and its 24th march , i still didn t got my periods.I am taking triphala churna and recently got heavy diarrhea too. It was like around 10 days , so is it the reason for delaying my periods. Does Triphala churna stops period,or is it due to diarrhea for long time.
